[jira] [Updated] (SPARK-50793) MySQL JDBC Connector failed to cast DOUBLE, LONGTEXT, SMALLINT, INTEGER, BIGINT and BLOB types
[ https://issues.apache.org/jira/browse/SPARK-50793?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Xiaoguang Sun updated SPARK-50793:
----------------------------------
Summary: MySQL JDBC Connector failed to cast DOUBLE, LONGTEXT, SMALLINT, INTEGER, BIGINT and BLOB types (was: MySQL JDBC Connector failed to cast LONGTEXT, SMALLINT, INTEGER, BIGINT and BLOB types)
> MySQL JDBC Connector failed to cast DOUBLE, LONGTEXT, SMALLINT, INTEGER, BIGINT and BLOB types
> ----------------------------------------------------------------------------------------------
>
> Key: SPARK-50793
> URL: https://issues.apache.org/jira/browse/SPARK-50793
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.0.0, 3.4.4, 3.5.4
> Reporter: Xiaoguang Sun
> Priority: Major
> Labels: pull-request-available
>
> In MySQL, the type identifier used in cast function is different from their type name. MySQL connector generates SQL which fails with cast.
> These are the steps to reproduce.
> # CREATE TABLE test_cast(string_col STRING, short_col SHORT, integer_col INTEGER, long_col LONG, binary_col BINARY, double_col DOUBLE);
> # INSERT INTO test_cast VALUES('0', 0, 0, 0, x'30', 0.0);
> # SELECT * FROM test_cast WHERE CAST(string_col AS BINARY) = binary_col;
> # SELECT * FROM test_cast WHERE CAST(string_col AS SHORT) = short_col;
> # SELECT * FROM test_cast WHERE CAST(string_col AS INTEGER) = integer_col;
> # SELECT * FROM test_cast WHERE CAST(string_col AS LONG) = long_col;
> # SELECT * FROM test_cast WHERE CAST(short_col AS STRING) = '0';
> # SELECT * FROM test_cast WHERE CAST(integer_col AS STRING) = '0';
> # SELECT * FROM test_cast WHERE CAST(long_col AS STRING) = '0';
> # SELECT * FROM test_cast WHERE CAST(binary_col AS STRING) = '0';
> # SELECT * FROM test_cast WHERE CAST(double_col AS STRING) = '0';
