NAME

sqlite3_value_subtype — finding the subtype of SQL values

SYNOPSIS

#include <sqlite3.h>

unsigned int
sqlite3_value_subtype(sqlite3_value*);

DESCRIPTION

The sqlite3_value_subtype(V) function returns the subtype for an application-defined SQL function argument V. The subtype information can be used to pass a limited amount of context from one SQL function to another. Use the sqlite3_result_subtype() routine to set the subtype for the return value of an SQL function.

Every application-defined SQL function that invoke this interface should include the SQLITE_SUBTYPE property in the text encoding argument when the function is registered. If the SQLITE_SUBTYPE property is omitted, then sqlite3_value_subtype() might return zero instead of the upstream subtype in some corner cases.

IMPLEMENTATION NOTES

These declarations were extracted from the interface documentation at line 5795.
