Fix two things:
1. Fix that the MySQL table displays the garbled code even if the UTF8 is specified for table.
2. Fix that `test_mysql_jdbc_catalog.out` lack of returned data for table `ex_tb13`.
Issue Number: close #xxx
I add jdbc catalog for doris multi-catalog feature.
Currently, the jdbc catalog only supports MYSQL DBMS.
TODO:
support for postgre DB
Support for other databases.
Problem summary
For jdbc catalog, we can create catalog like:
CREATE CATALOG jdbc4 PROPERTIES (
"type"="jdbc",
"jdbc.user"="root",
"jdbc.password"="123456",
"jdbc.jdbc_url" = "jdbc:mysql://127.0.0.1:13396/demo?yearIsDateType=false",
"jdbc.driver_url" = "file:/mnt/disk2/ftw/tools/jar/mysql-connector-java-5.1.47/mysql-connector-java-5.1.47.jar",
"jdbc.driver_class" = "com.mysql.jdbc.Driver"
);
Note:
yearIsDateType is a param of jdbc:
If yearIsDateType configuration property is set to false, then the returned object type is java.sql.Short. If set to true (the default), then the returned object is of type java.sql.Date with the date set to January 1st, at midnight.
To compat with mysql, we force the use of yearIsDateType=false in FE. if user sets yearIsDateType=true, doris FE will force to change yearIsDateType=false.
1. Modify default behavior of `build.sh`
The `BUILD_JAVA_UDF` is default ON, so that jvm is needed for compilation and runtime.
2. Add docker-compose for MySQL 5.7, PostgreSQL 14 and Hive 2
See `docker/thirdparties/docker-compose`.
3. Add some regression test cases for jdbc query on MySQL, PG and Hive Catalog
The default is `false`, if set to true, you need first start docker for MySQL/PG/Hive.
4. Support `if not exists` and `if exists` for create/drop resource and create/drop encryptkey
