Member Function Documentation

◆ getMaximumPrecision()

int FreetdsSqlUtil::FreetdsDatabase::getMaximumPrecision ( )

Returns the maximum precision for numeric or decimal columns.

Returns: -1 means, no maximum

Since: FreeSqlUtil 1.4.2

◆ listFunctionsImpl()

list<string> FreetdsSqlUtil::FreetdsDatabase::listFunctionsImpl ( )

private

returns a list of string function names in the database

The function names will include arguments in parentheses after the names

Returns: a list of string function names in the database

◆ listProceduresImpl()

list<string> FreetdsSqlUtil::FreetdsDatabase::listProceduresImpl ( )

private

since FreeTDS only supports functions, this method is identical to listFunctionsImpl()

See also: listFunctionsImpl()

◆ requiresScale()

bool FreetdsSqlUtil::FreetdsDatabase::requiresScale ( )

Returns True if the driver requires a scale to support decimal values in numeric or decimal columns.

Returns: True if the driver requires a scale to support decimal values in numeric or decimal columns

Since: FreeSqlUtil 1.4.2
