Abstract
A computer-implemented method for a database constraint relationship check, includes performing a data manipulation language (DML) operation of a first transaction for a target data table in the database. A submission stage is entered. A corresponding current transaction version number is determined for a target data record obtained and each latest related data record visible to the first transaction is read from the target data table or an associated data table of the target data table. A mutual limitation relationship exists between field values corresponding to a target field in the target data record and each related data record. A constraint relationship check is performed on a target field value corresponding to the target field in the target data record based on each related data record. The first transaction is submitted if the constraint relationship check succeeds or the first transaction is rolled back otherwise.
