[jira] [Updated] (IGNITE-11538) SQL: Support new features
(precision, scale, etc) in JDBC drivers
[ https://issues.apache.org/jira/browse/IGNITE-11538?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Pavel Kuznetsov updated IGNITE-11538:
-------------------------------------
Description:
Currently JDBC result set meta data return dummy value (0) for the precision and scale, but we already have all the info to return correct values.
*Both thin and v2 driver are affected.*
See
{{org.apache.ignite.internal.jdbc2.JdbcResultSetMetadata#getPrecision}} - dummy 0
{{org.apache.ignite.internal.processors.odbc.jdbc.JdbcQueryCursor#meta}} - thin driver actually uses v1 version of the JdbcColumnMeta; {{org.apache.ignite.internal.jdbc.thin.JdbcThinResultSetMetadata#getPrecision}} ignores precision and returns 0;
was:
Currently JDBC result set meta data return dummy value (0 or -1 depending on the driver) for the precision and scale, but we already have all the info to return correct values.
*Both thin and v2 driver are affected.*
See
{{org.apache.ignite.internal.jdbc2.JdbcResultSetMetadata#getPrecision}} - dummy 0
{{org.apache.ignite.internal.processors.odbc.jdbc.JdbcQueryCursor#meta}} - thin driver actually uses v1 version of the JdbcColumnMeta which returns -1
