[jira] [Updated] (IGNITE-5939) ODBC: SQLColAttributes should work
with legacy attribute codes.
[ https://issues.apache.org/jira/browse/IGNITE-5939?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Igor Sapego updated IGNITE-5939:
--------------------------------
Description:
According to https://docs.microsoft.com/en-us/sql/odbc/reference/syntax/sqlcolattribute-function
{quote}
The #define values of the ODBC 2.x {{FieldIdentifiers}} {{SQL_COLUMN_LENGTH}}, {{SQL_COLUMN_PRECISION}}, and {{SQL_COLUMN_SCALE}} are different from the #define values of the ODBC 3.x {{FieldIdentifiers}} {{SQL_DESC_PRECISION}}, {{SQL_DESC_SCALE}}, and {{SQL_DESC_LENGTH}}. An ODBC 2.x driver need only support the ODBC 2.x values. An ODBC 3.x driver must support both "{{SQL_COLUMN}}" and "{{SQL_DESC}}" values for these three {{FieldIdentifiers}}. These values are different because precision, scale, and length are defined differently in ODBC 3.x than they were in ODBC 2.x.
{quote}
Currently, {{SQLColAttributes}} does not work with these three identifiers in our driver. Need to be fixed.
