KSQL_EXEC(3) Library Functions Manual KSQL_EXEC(3)

execute a standalone statement not returning any values

library “ksql”

#include <sys/types.h>
#include <stdint.h>
#include <ksql.h>
enum ksqlc
ksql_exec(struct ksql *sql, const char *stmt, size_t id);

The ksql_exec function executes stmt on an open database connection sql. The id is used to identify the statement in error messages and should uniquely identify the statement.
If a non-empty cfg->stmts structure documented in ksql_cfg_defaults(3) is passed to ksql_alloc(3) or ksql_alloc_child(3), the stored statement is looked up by id and the stmt value is ignored. If id is not a valid index of cfg->stmts.stmtsz, the program is immediately terminated.
This function handles a locked database (specifically, SQLITE_BUSY, SQLITE_LOCKED, or SQLITE_PROTOCOL) by sleeping for a random interval, then trying again infinitely.

This function returns KSQL_NOTOPEN if the database connection has not been opeend, KSQL_DB on database errors, or KSQL_OK otherwise.
