SQLite, a widely used embedded SQL database engine, provides a comprehensive list of error codes to help diagnose and handle various scenarios that can occur during database operations. One such error code is SQLITE_OK.


SQLITE_OK is not actually an error code in the traditional sense; rather, it signifies that the operation has completed successfully. When SQLite returns SQLITE_OK, it means that the last operation was executed without any errors, indicating a successful outcome. This code is fundamental to error handling in SQLite, as it allows developers to check the result of database operations and ensure that they proceed as expected without encountering any issues.

The SQLITE_OK error code has a numeric value of 0. This is a standard practice in many programming environments, where a return code of 0 often signifies success, and non-zero values indicate various types of errors or warnings.

Context of Use

SQLite functions use SQLITE_OK to inform the calling application that an operation has been performed successfully. This can include a wide range of operations such as:

Opening a new database connection.
Executing a SQL statement.
Finalizing a prepared statement.
Starting, committing, or rolling back a transaction.


Understanding SQLITE_OK is crucial for developers working with SQLite, as it is the baseline against which error states are measured. When a SQLite API call returns SQLITE_OK, developers can proceed with the next steps in their application logic, knowing that the previous operation did not encounter any problems.

Handling SQLITE_OK

In practice, when a SQLite function returns SQLITE_OK, it typically does not require any special error handling. The return code can be used in conditional checks to ensure that the program only proceeds if the database operation was successful. Here’s a simple example in C:


int main(void) {
    sqlite3 *db;
    char *err_msg = 0;
    int rc = sqlite3_open("test.db", &db);
    if (rc != SQLITE_OK) {
        fprintf(stderr, "Cannot open database: %s\n", sqlite3_errmsg(db));
        return 1;
    rc = sqlite3_exec(db, "CREATE TABLE Friends(Id INTEGER PRIMARY KEY, Name TEXT);", 0, 0, &err_msg);
    if (rc != SQLITE_OK ) {
        fprintf(stderr, "SQL error: %s\n", err_msg);
        return 1;
    return 0;

In this example, sqlite3_open and sqlite3_exec functions return SQLITE_OK if they succeed, indicating the database has been successfully opened and the table has been created without any errors. Otherwise, the error message is printed to the standard error output, and the program terminates with an error status.


SQLITE_OK plays a fundamental role in SQLite error handling, serving as an indicator of success for various database operations. By checking for this code, developers can confidently manage the flow of their applications, ensuring that they only proceed when database interactions are error-free. Understanding and correctly handling SQLITE_OK is essential for robust and reliable application development using SQLite.
