Re: [sqlite] Prepared Statement (select * from x where y in ());
Long ago and far away, I build a database abstraction layer which used
?@ for this. So you'd say something like:
stmt = prepare("select * from table where xyz in (?@)");
bind_array(stmt, 0, arrayRef);
The library would take the array, quote each element, and separate
them with commas. It was pretty nice when you needed it.
Unfortunately, this wasn't for sqlite :-).
One option would be to write code to build the statement with the
right number of ?, then bind that many. Very annoying.
Another option would be to create a temporary table, run through the
array doing individual INSERT statements, then "select * from table
where xyz in (select * from temp_table)". Also very annoying.

Problem is as shown below,

bind_text("'ab','xy','zx','123'")
bind_text will append '' at the begining and at end making it as one string
rather
than ab,xy,zx.

[sqlite] Prepared Statement (select * from x where y in ());
HI, 1)How can we prepare a SQliteStatement for the following type of select, select * from tablename where column in (?); ?: we don;t know the length of this string. 2) Can we mix SqliteStatement and sqlite3_exec functions? regads ragha ** This email and its attachments contain confidential information from HUAWEI, which is intended only for the person or entity whose address is listed above.
