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

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

open2 :: Utf8 -> Int -> Maybe Utf8 -> IO (Either (Error, Utf8) Database) #

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

close :: Database -> IO (Either Error ()) #

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

errcode :: Database -> IO Error #

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

extendedErrcode :: Database -> IO Error #

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

errmsg :: Database -> IO Utf8 #

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

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

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 #

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 ()) #

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) ()) #

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

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

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

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

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.
-> [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)) #

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

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

getStatementDatabase :: Statement -> IO Database #

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

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

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

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

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 ()) #

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

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

clearBindings :: Statement -> IO () #

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

Set all parameters in the prepared statement to null.

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

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 #

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) #

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

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

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

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

bindText :: Statement -> ParamIndex -> Utf8 -> IO (Either Error ()) #

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

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

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

# Reading the result row

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

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

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

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

columnText :: Statement -> ColumnIndex -> IO Utf8 #

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

# control loading of extensions

setLoadExtensionEnabled :: Database -> Bool -> IO (Either Error ()) #

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

Enable or disable extension loading.

# 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.

totalChanges :: Database -> IO Int #

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 #

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 #

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 ()) #

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 #

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

funcResultText :: FuncContext -> Utf8 -> 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 |
-> 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 ()) #

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`.

# Incremental blob I/O

blobOpen #

Arguments

:: Database |
-> Utf8 | The symbolic name of the database (e.g. "main").
-> Utf8 | The table name.
-> Utf8 | The column name.

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.
