Description

This API is a slightly lower-level version of Database.SQLite3. Namely:

It returns errors instead of throwing them.
It only uses cheap conversions. None of these bindings convert from String or Text.

Connection management

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

errmsg :: Database -> IO Utf8 Source #

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

setExtendedResultCodes :: Database -> Bool -> IO (Either Error ()) Source #

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

setTrace :: Database -> Maybe (Utf8 -> IO ()) -> IO () Source #

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

Enable/disable tracing of SQL execution. Tracing can be disabled by setting Nothing as the logger callback.

Warning: If the logger callback throws an exception, your whole program will crash. Enable only for debugging!

getAutoCommit :: Database -> IO Bool Source #

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

Return True if the connection is in autocommit mode, or False if a transaction started with BEGIN is still active.

Be warned that some errors roll back the transaction automatically, and that ROLLBACK will throw an error if no transaction is active. Use getAutoCommit to avoid such an error:

 autocommit <- getAutoCommit conn
 when (not autocommit) $
     exec conn "ROLLBACK"

setSharedCacheEnabled :: Bool -> IO (Either Error ()) Source #

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

Enable or disable shared cache for all future connections.

Simple query execution

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

exec :: Database -> Utf8 -> IO (Either (Error, Utf8) ()) Source #

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

execWithCallback :: Database -> Utf8 -> ExecCallback -> IO (Either (Error, Utf8) ()) Source #

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

If the callback throws an exception, it will be rethrown by execWithCallback.

type ExecCallback Source #

Arguments

= ColumnCount	Number of columns, which is the number of items in the following lists. This will be the same for every row.
-> [Utf8]	List of column names. This will be the same for every row.
-> [Maybe Utf8]	List of column values, as returned by `columnText`.
-> IO ()

Statement management

prepare :: Database -> Utf8 -> IO (Either Error (Maybe Statement)) Source #

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

If the query contains no SQL statements, this returns Right Nothing.

getStatementDatabase :: Statement -> IO Database Source #

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

step :: Statement -> IO (Either Error StepResult) Source #

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

stepNoCB :: Statement -> IO (Either Error StepResult) Source #

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

reset :: Statement -> IO (Either Error ()) Source #

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

Warning:

If the most recent step call failed, this will return the corresponding error.
This does not reset the bindings on a prepared statement. Use clearBindings to do that.

finalize :: Statement -> IO (Either Error ()) Source #

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

Warning: If the most recent step call failed, this will return the corresponding error.

clearBindings :: Statement -> IO () Source #

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

Set all parameters in the prepared statement to null.

statementSql :: Statement -> IO (Maybe Utf8) Source #

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

Return a copy of the original SQL text used to compile the statement.

Parameter and column information

bindParameterCount :: Statement -> IO ParamIndex Source #

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 Utf8) Source #

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

bindParameterIndex :: Statement -> Utf8 -> IO (Maybe ParamIndex) Source #

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

Enable or disable extension loading.

Result statistics

lastInsertRowId :: Database -> IO Int64 Source #

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

changes :: Database -> IO Int Source #

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.

totalChanges :: Database -> IO Int Source #

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

Return the total number of row changes caused by INSERT, DELETE, or UPDATE statements since the Database was opened.

Create custom SQL functions

createFunction Source #

Arguments

:: Database
-> Utf8	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 (Either Error ())

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

Create a custom SQL function or redefine the behavior of an existing function.

createAggregate Source #

Arguments

:: Database
-> Utf8	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 (Either Error ())

Like createFunction except that it creates an aggregate function.

deleteFunction :: Database -> Utf8 -> Maybe ArgCount -> IO (Either Error ()) Source #

Delete an SQL function (scalar or aggregate).

Extract function arguments

funcArgCount :: FuncArgs -> ArgCount Source #

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

funcResultNull :: FuncContext -> IO () Source #

getFuncContextDatabase :: FuncContext -> IO Database Source #

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

Create custom collations

createCollation Source #

Arguments

:: Database
-> Utf8	Name of the collation.
-> (Utf8 -> Utf8 -> Ordering)	Comparison function.
-> IO (Either Error ())

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

deleteCollation :: Database -> Utf8 -> IO (Either Error ()) Source #

Delete a collation.

Interrupting a long-running query

interrupt :: Database -> IO () Source #

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.

Incremental blob I/O

blobOpen Source #

-> Utf8	The table name.
-> Utf8	The column name.

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

blobReopen Source #

Arguments

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

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

blobBytes :: Blob -> IO Int Source #

newtype ParamIndex Source #

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

When a query is prepared, 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.
