# NAME

sqlite3changeset_op — Obtain The Current Operation From A Changeset Iterator

# SYNOPSIS

int
sqlite3changeset_op(sqlite3_changeset_iter *pIter, const char **pzTab, int *pnCol, int *pOp, int *pbIndirect );

# DESCRIPTION

The pIter argument passed to this function may either be an iterator passed to a conflict-handler by sqlite3changeset_apply(), or an iterator created by sqlite3changeset_start(). In the latter case, the most recent call to sqlite3changeset_next() must have returned SQLITE_ROW. If this is not the case, this function returns SQLITE_MISUSE.
If argument pzTab is not NULL, then *pzTab is set to point to a nul-terminated utf-8 encoded string containing the name of the table affected by the current change. The buffer remains valid until either sqlite3changeset_next() is called on the iterator or until the conflict-handler function returns. If pnCol is not NULL, then *pnCol is set to the number of columns in the table affected by the change. If pbIncorrect is not NULL, then *pbIndirect is set to true (1) if the change is an indirect change, or false (0) otherwise. See the documentation for sqlite3session_indirect() for a description of direct and indirect changes. Finally, if pOp is not NULL, then *pOp is set to one of SQLITE_INSERT, SQLITE_DELETE or SQLITE_UPDATE, depending on the type of change that the iterator currently points to.
If no error occurs, SQLITE_OK is returned. If an error does occur, an SQLite error code is returned. The values of the output variables may not be trusted in this case.
