decodeError :: CError -> Error Source #

Note that this is a partial function. If the error code is invalid, or perhaps introduced in a newer version of SQLite but this library has not been updated to support it, the result is undefined.

To be clear, if decodeError fails, it is undefined behavior, not an exception you can handle.

Therefore, do not use direct-sqlite with a different version of SQLite than the one bundled (currently, 3.7.13). If you do, ensure that decodeError and decodeColumnType are still exhaustive.

Indices

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

Conversion to and from FFI types

class FFIType public ffi | public -> ffi, ffi -> public where Source #

The Database.SQLite3 and Database.SQLite3.Direct modules use higher-level representations of some types than those used in the FFI signatures (Database.SQLite3.Bindings). This typeclass helps with the conversions.
