Error
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, 3.24.0). 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 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.
