Hi all,
I'm using sqlite 3.6.22-1 in ubuntu 10.04.
If a precompiled statement become expired, and sqlite3_step() is called,
documentation says that it will fail with a SQLITE_SCHEMA error.
/* Opcode: Expire P1 * * * *
**
** Cause precompiled statements to become expired. An expired
statement
** fails with an error code of SQLITE_SCHEMA if it is ever
executed
** (via sqlite3_step()).
**
** If P1 is 0, then all SQL statements become expired. If P1 is
non-zero,
** then only the currently executing statement is affected.
*/
case OP_Expire: {
if( !pOp->p1 ){
sqlite3ExpirePreparedStatements(db);
}else{
p->expired = 1;
}
break;
}
Above, p->expired is set to 1 for the current statement. But when
opening a read-only or read-write cursor for the database table during a
sqlite3_step() with that statement, if the expired flag is found set,
SQLITE_ABORT is set as error code, instead of SQLITE_SCHEMA, as the
documentation says, which seems an error:
case OP_OpenRead:
case OP_OpenWrite: {
int nField;
KeyInfo *pKeyInfo;
int p2;
int iDb;
int wrFlag;
Btree *pX;
VdbeCursor *pCur;
Db *pDb;
if( p->expired ){
-- rc = SQLITE_ABORT;
++ rc = SQLITE_SCHEMA;
break;
}
Now, apart from the issue above, is there any other method to know if a
precompiled statement expired? I see that sqlite3_expired() is marked as
deprecated, so what would be the equivalent?
Cheers,
