The following test program reports that the PRAGMA fails:
<blockquote><verbatim>
#include <stdio.h>
#include "sqlite3.h"
int main(void){
sqlite3 *db3;
char *errmsg;
int err;
sqlite3_open("test.db", &db3);
err = sqlite3_exec(db3, "PRAGMA case_sensitive_like=1;", 0, 0, &errmsg);
if (err != SQLITE_OK){
printf("Error %d: %s\n", err, errmsg);
sqlite3_free(errmsg);
}
return 0;
}
</verbatim></blockquote>
This problem was reported on the mailing list by Greg Stein. Investigation
shows that the PRAGMA actually works; it simply returns an SQLITE_SCHEMA
error code instead of SQLITE_OK. The problem was introduced by
check-in [957b2ab67c61] by the removal of "p->expired = 0;" from
the sqlite3VdbeAddOp3(). The case_sensitive_like function causes
a new LIKE function to be registered, which sets "p->expired = 1",
leading to the error. It is unclear (yet) why this problem was not
picked up by tests.
