R-23929-31743-58027-02127-28995-37198-56222-58306 tcl slt th3 src

These routines work just like the corresponding column access functions except that these routines take a single protected sqlite3_value object pointer instead of a sqlite3_stmt* pointer and an integer column number.

The sqlite3_value_text16() interface extracts a UTF-16 string in the native byte-order of the host machine.

The sqlite3_value_text16be() and sqlite3_value_text16le() interfaces extract UTF-16 strings as big-endian and little-endian respectively.

If sqlite3_value object V was initialized using sqlite3_bind_pointer(S,I,P,X,D) or sqlite3_result_pointer(C,P,X,D) and if X and Y are strings that compare equal according to strcmp(X,Y), then sqlite3_value_pointer(V,Y) will return the pointer P.

Otherwise, sqlite3_value_pointer(V,Y) returns a NULL.

The sqlite3_value_type(V) interface returns the datatype code for the initial datatype of the sqlite3_value object V. The returned value is one of SQLITE_INTEGER, SQLITE_FLOAT, SQLITE_TEXT, SQLITE_BLOB, or SQLITE_NULL.

R-23299-15149-12260-14236-54625-56854-20927-10236 tcl slt th3 src

The sqlite3_value_numeric_type() interface attempts to apply numeric affinity to the value. This means that an attempt is made to convert the value to an integer or floating point. If such a conversion is possible without loss of information (in other words, if the value is a string that looks like a number) then the conversion is performed. Otherwise no conversion occurs. The datatype after conversion is returned.

Within the xUpdate method of a virtual table, the sqlite3_value_nochange(X) interface returns true if and only if the column corresponding to X is unchanged by the UPDATE operation that the xUpdate method call was invoked to implement and if and the prior xColumn method call that was invoked to extracted the value for that column returned without setting a result (probably because it queried sqlite3_vtab_nochange() and found that the column was unchanging).

Within an xUpdate method, any value for which sqlite3_value_nochange(X) is true will in all other respects appear to be a NULL value.
