ifx_prepare -- Prepare an SQL-statement for execution
Description
int ifx_prepare (string query, int conn_id [, int cursor_def, mixed
blobidarray])
Returns a integer result_id for use by
ifx_do(). Sets affected_rows for retrieval by the ifx_affected_rows() function.
Prepares query on connection conn_id. For "select-type"
queries a cursor is declared and opened. The optional cursor_type parameter allows
you to make this a "scroll" and/or "hold" cursor. It's a bitmask and can be either IFX_SCROLL,
IFX_HOLD, or both or'ed together.
For either query type the estimated number of affected rows is saved for retrieval by ifx_affected_rows().
If you have BLOB (BYTE or TEXT) columns in the query, you can add a
blobidarray parameter containing the corresponding "blob ids", and you should replace
those columns with a "?" in the query text.
If the contents of the TEXT (or BYTE) column allow it, you can also use
"ifx_textasvarchar(1)" and "ifx_byteasvarchar(1)". This allows you to treat TEXT (or BYTE) columns
just as if they were ordinary (but long) VARCHAR columns for select queries, and you don't need to
bother with blob id's.
With ifx_textasvarchar(0) or ifx_byteasvarchar(0) (the default situation), select queries
will return BLOB columns as blob id's (integer value). You can get the value of the blob as a
string or file with the blob functions (see below).
