Status Parameter (stmt) Constants

The following table lists the status parameter (stmt) constants:

Constant Meaning
STMTSTATUS_FULLSCAN_STEP This is the number of times that SQLite has stepped forward in a table as part of a full table scan. Large numbers for this counter may indicate opportunities for performance improvement through careful use of indices.
STMTSTATUS_SORT This is the number of sort operations that have occurred. A non-zero value in this counter may indicate an opportunity to improvement performance through careful use of indices.
STMTSTATUS_AUTOINDEX This is the number of rows inserted into transient indices that were created automatically in order to help joins run faster. A non-zero value in this counter may indicate an opportunity to improvement performance by adding permanent indices that do not need to be reinitialized each time the statement is run.
STMTSTATUS_VM_STEP This is the number of virtual machine operations executed by the prepared statement if that number is less than or equal to 2147483647. The number of virtual machine operations can be used as a proxy for the total work done by the prepared statement. If the number of virtual machine operations exceeds 2147483647 then the value returned by this statement status code is undefined.
