◆ getSavepointHelperImpl()

AbstractSavepointHelper MssqlSqlUtilBase::MssqlTable::getSavepointHelperImpl ( __7_ string savepoint)
protected

get DB-specific savepoint helper

Parameters
savepointthe savepoint string, if not given a unique savepoint string will be generated
Since
SqlUtil 1.6

◆ getSqlValueImpl()

__7_ string MssqlSqlUtilBase::MssqlTable::getSqlValueImpl ( auto v)
protected

returns a string for use in SQL queries representing the DB-specific value of the argument

returns NOTHING if the type cannot be converted to an SQL string

◆ getUpsertClosure()

code MssqlSqlUtilBase::MssqlTable::getUpsertClosure ( hash< auto > row,
int upsert_strategy = UpsertAuto,
__7_ hash opt )

returns a closure for performing upserts

if the underlying dataserver supports an optimized MERGE statement (Microsoft SQL Server 2008+), the upsert_strategy argument is ignored and a closure using a merge statement is returned, otherwise the standard upsert closure is returned according to SqlUtil::AbstractTable::getUpsertClosure()

◆ isDuplicateRowErrorImpl()

bool MssqlSqlUtilBase::MssqlTable::isDuplicateRowErrorImpl ( hash< ExceptionInfo > ex)
protected

Returns True if the exception was raised because of a duplicate row / key error.

Since
MssqlSqlUtilBase 1.4.1
