# Connection management

withDatabase #

Arguments

:: Text | connection string
-> (Database -> IO a) | user program
-> IO a |

Manage a connection to a database in an exception-safe way (with `bracket`)

open :: Text -> IO Database #

https://www.sqlite.org/c3ref/open.html

open2 :: Text -> [SQLOpenFlag] -> SQLVFS -> IO Database #

https://www.sqlite.org/c3ref/open.html

close :: Database -> IO () #

https://www.sqlite.org/c3ref/close.html

# Simple query execution

https://sqlite.org/c3ref/exec.html

exec :: Database -> Text -> IO () #

Execute zero or more SQL statements delimited by semicolons.

execPrint :: Database -> Text -> IO () #

Like `exec`, but print result rows to `stdout`.

This is mainly for convenience when experimenting in GHCi. The output format may change in the future.

execWithCallback :: Database -> Text -> ExecCallback -> IO () #

Like `exec`, but invoke the callback for each result row.

type ExecCallback #

Arguments

= ColumnCount | Number of columns, which is the number of items in the following lists. This will be the same for every row.
-> [Text] | List of column names. This will be the same for every row.
-> [Maybe Text] | List of column values, as returned by `columnText`.
-> IO () |

# Statement management

withStatement #

Arguments

:: Database | DB connection
-> Text | SQL statement
-> (Statement -> IO a) | User program
-> IO a |

Bracket `prepare` and `finalize`. Useful for stepping multiple times through a `Statement`

prepare :: Database -> Text -> IO Statement #

https://www.sqlite.org/c3ref/prepare.html

Unlike `exec`, `prepare` only executes the first statement, and ignores subsequent statements.

If the query string contains no SQL statements, this `fail`s.

prepareUtf8 :: Database -> Utf8 -> IO Statement #

https://www.sqlite.org/c3ref/prepare.html

It can help to avoid redundant Utf8 to Text conversion if you already have Utf8

If the query string contains no SQL statements, this `fail`s.

step :: Statement -> IO StepResult #

https://www.sqlite.org/c3ref/step.html

stepNoCB :: Statement -> IO StepResult #

https://www.sqlite.org/c3ref/step.html

Faster step for statements that don't callback to Haskell functions (e.g. by using custom SQL functions).

reset :: Statement -> IO () #

https://www.sqlite.org/c3ref/reset.html

Note that in the C API, `sqlite3_reset` returns an error code if the most recent `sqlite3_step` indicated an error. We do not replicate that behavior here. `reset` never throws an exception.

finalize :: Statement -> IO () #

https://www.sqlite.org/c3ref/finalize.html

Like `reset`, `finalize` never throws an exception.

clearBindings :: Statement -> IO () #

https://www.sqlite.org/c3ref/clear_bindings.html

Set all parameters in the prepared statement to null.

# Parameter and column information

bindParameterCount :: Statement -> IO ParamIndex #

https://www.sqlite.org/c3ref/bind_parameter_count.html

This returns the index of the largest (rightmost) parameter. Note that this is not necessarily the number of parameters. If numbered parameters like `?5` are used, there may be gaps in the list.

See `ParamIndex` for more information.

bindParameterName :: Statement -> ParamIndex -> IO (Maybe Text) #

https://www.sqlite.org/c3ref/bind_parameter_name.html

Return the N-th SQL parameter name.

Named parameters are returned as-is. E.g. ":v" is returned as `Just ":v"`. Unnamed parameters, however, are converted to `Nothing`.

Note that the parameter index starts at 1, not 0.

columnCount :: Statement -> IO ColumnCount #

https://www.sqlite.org/c3ref/column_count.html

columnName :: Statement -> ColumnIndex -> IO (Maybe Text) #

https://www.sqlite.org/c3ref/column_name.html

Return the name of a result column. If the column index is out of range, return `Nothing`.

# Binding values to a prepared statement

https://www.sqlite.org/c3ref/bind_blob.html

bindSQLData :: Statement -> ParamIndex -> SQLData -> IO () #

If the index is not between 1 and `bindParameterCount` inclusive, this fails with `ErrorRange`. Otherwise, it succeeds, even if the query skips this index by using numbered parameters.

Example:

    > stmt <- prepare conn "SELECT ?1, ?3, ?5"
    > bindSQLData stmt 1 (SQLInteger 1)
    > bindSQLData stmt 2 (SQLInteger 2)
    > bindSQLData stmt 6 (SQLInteger 6)
    *** Exception: SQLite3 returned ErrorRange while attempting to perform bind int64.
    > step stmt >> columns stmt
    [SQLInteger 1,SQLNull,SQLNull]

bind :: Statement -> [SQLData] -> IO () #

Convenience function for binding values to all parameters. This will `fail` if the list has the wrong number of parameters.

bindNamed :: Statement -> [(Text, SQLData)] -> IO () #

Convenience function for binding named values to all parameters. This will `fail` if the list has the wrong number of parameters or if an unknown name is used.

Example:

    stmt <- prepare conn "SELECT :foo + :bar"
    bindNamed stmt [(":foo", SQLInteger 1), (":bar", SQLInteger 2)]

bindInt :: Statement -> ParamIndex -> Int -> IO () #

bindInt64 :: Statement -> ParamIndex -> Int64 -> IO () #

bindDouble :: Statement -> ParamIndex -> Double -> IO () #

bindText :: Statement -> ParamIndex -> Text -> IO () #

bindBlob :: Statement -> ParamIndex -> ByteString -> IO () #

bindZeroBlob :: Statement -> ParamIndex -> Int -> IO () #

bindNull :: Statement -> ParamIndex -> IO () #

# Reading the result row

https://www.sqlite.org/c3ref/column_blob.html

Warning: `column` and `columns` will throw a `DecodeError` if any `TEXT` datum contains invalid UTF-8.

column :: Statement -> ColumnIndex -> IO SQLData #

columns :: Statement -> IO [SQLData] #

typedColumns :: Statement -> [Maybe ColumnType] -> IO [SQLData] #

This avoids extra API calls using the list of column types. If passed types do not correspond to the actual types, the values will be converted according to the rules at https://www.sqlite.org/c3ref/column_blob.html. If the list contains more items that number of columns, the result is undefined.

columnType :: Statement -> ColumnIndex -> IO ColumnType #

columnInt64 :: Statement -> ColumnIndex -> IO Int64 #

columnDouble :: Statement -> ColumnIndex -> IO Double #

columnText :: Statement -> ColumnIndex -> IO Text #

This will throw a `DecodeError` if the datum contains invalid UTF-8. If this behavior is undesirable, you can use `columnText` from Database.SQLite3.Direct, which does not perform conversion to `Text`.

columnBlob :: Statement -> ColumnIndex -> IO ByteString #

# Result statistics

lastInsertRowId :: Database -> IO Int64 #

https://www.sqlite.org/c3ref/last_insert_rowid.html

changes :: Database -> IO Int #

https://www.sqlite.org/c3ref/changes.html

Return the number of rows that were changed, inserted, or deleted by the most recent `INSERT`, `DELETE`, or `UPDATE` statement.

# Create custom SQL functions

createFunction #

Arguments

:: Database |
-> Text | Name of the function.
-> Maybe ArgCount | Number of arguments. `Nothing` means that the function accepts any number of arguments.
-> Bool | Is the function deterministic?
-> (FuncContext -> FuncArgs -> IO ()) | Implementation of the function.
-> IO () |

https://sqlite.org/c3ref/create_function.html

Create a custom SQL function or redefine the behavior of an existing function. If the function is deterministic, i.e. if it always returns the same result given the same input, you can set the boolean flag to let `sqlite` perform additional optimizations.

createAggregate #

Arguments

:: Database |
-> Text | Name of the function.
-> Maybe ArgCount | Number of arguments.
-> a | Initial aggregate state.
-> (FuncContext -> FuncArgs -> a -> IO a) | Process one row and update the aggregate state.
-> (FuncContext -> a -> IO ()) | Called after all rows have been processed. Can be used to construct the returned value from the aggregate state.
-> IO () |

Like `createFunction` except that it creates an aggregate function.

deleteFunction :: Database -> Text -> Maybe ArgCount -> IO () #

Delete an SQL function (scalar or aggregate).

## Extract function arguments

funcArgCount :: FuncArgs -> ArgCount #

funcArgType :: FuncArgs -> ArgIndex -> IO ColumnType #

funcArgInt64 :: FuncArgs -> ArgIndex -> IO Int64 #

funcArgDouble :: FuncArgs -> ArgIndex -> IO Double #

funcArgText :: FuncArgs -> ArgIndex -> IO Text #

funcArgBlob :: FuncArgs -> ArgIndex -> IO ByteString #

## Set the result of a function

funcResultSQLData :: FuncContext -> SQLData -> IO () #

funcResultInt64 :: FuncContext -> Int64 -> IO () #

funcResultDouble :: FuncContext -> Double -> IO () #

funcResultText :: FuncContext -> Text -> IO () #

funcResultBlob :: FuncContext -> ByteString -> IO () #

funcResultZeroBlob :: FuncContext -> Int -> IO () #

funcResultNull :: FuncContext -> IO () #

getFuncContextDatabase :: FuncContext -> IO Database #

https://www.sqlite.org/c3ref/context_db_handle.html

# Create custom collations

createCollation #

Arguments

:: Database |
-> Text | Name of the collation.
-> (Text -> Text -> Ordering) | Comparison function.
-> IO () |

https://www.sqlite.org/c3ref/create_collation.html

deleteCollation :: Database -> Text -> IO () #

Delete a collation.

# Interrupting a long-running query

interrupt :: Database -> IO () #

https://www.sqlite.org/c3ref/interrupt.html

Cause any pending operation on the `Database` handle to stop at its earliest opportunity. This simply sets a flag and returns immediately. It does not wait for the pending operation to finish.

You'll need to compile with `-threaded` for this to do any good. Without `-threaded`, FFI calls block the whole RTS, meaning `interrupt` would never run at the same time as `step`.

interruptibly :: Database -> IO a -> IO a #

Make it possible to interrupt the given database operation with an asynchronous exception. This only works if the program is compiled with base >= 4.3 and `-threaded`.

It works by running the callback in a forked thread. If interrupted, it uses `interrupt` to try to stop the operation.

# Incremental blob I/O

blobOpen #

Arguments

:: Database |
-> Text | The symbolic name of the database (e.g. "main").
-> Text | The table name.
-> Text | The column name.
-> Int64 | The `ROWID` of the row.
-> Bool | Open the blob for read-write.
-> IO Blob |

https://www.sqlite.org/c3ref/blob_open.html

Open a blob for incremental I/O.

blobClose :: Blob -> IO () #

https://www.sqlite.org/c3ref/blob_close.html

blobReopen #

Arguments

:: Blob |
-> Int64 | The `ROWID` of the row.
-> IO () |

https://www.sqlite.org/c3ref/blob_reopen.html

blobBytes :: Blob -> IO Int #

https://www.sqlite.org/c3ref/blob_bytes.html

blobRead #

Arguments

:: Blob |
-> Int | Number of bytes to read.
-> Int | Offset within the blob.
-> IO ByteString |

https://www.sqlite.org/c3ref/blob_read.html

blobReadBuf :: Blob -> Ptr a -> Int -> Int -> IO () #

blobWrite #

Arguments

:: Blob |
-> ByteString |
-> Int | Offset within the blob.
-> IO () |

https://www.sqlite.org/c3ref/blob_write.html

# Online Backup API

https://www.sqlite.org/backup.html and https://www.sqlite.org/c3ref/backup_finish.html

backupInit #

Arguments

:: Database | Destination database handle.
-> Text | Destination database name.

## Special integers

newtype ParamIndex #

Index of a parameter in a parameterized query. Parameter indices start from 1.

When a query is `prepare`d, SQLite allocates an array indexed from 1 to the highest parameter index. For example:

    >Right stmt <- prepare conn "SELECT ?1, ?5, ?3, ?"
    >bindParameterCount stmt
    ParamIndex 6

This will allocate an array indexed from 1 to 6 (`?` takes the highest preceding index plus one). The array is initialized with null values. When you bind a parameter with `bindSQLData`, it assigns a new value to one of these indices.

See https://www.sqlite.org/lang_expr.html#varparam for the syntax of parameter placeholders, and how parameter indices are assigned.
