SimpleJDBCCall handle out paramater with resultset - mysql

Question

I am using spring jdbc. I want result set with out param. separately i done but together i am not able to do.
CREATE DEFINER=`xxx`#`%` PROCEDURE `client_xxxx`(
IN p_xxxx TINYINT(1) UNSIGNED,
IN p_result SMALLINT(2) UNSIGNED,
OUT p_result BIT ) BEGIN
IF EXISTS(SELECT 1 FROM xxx WHERE xxx = 1 AND xxx = 1) THEN
SELECT ...;
SET p_result = 0;
ELSE
SELECT ...;
SET p_result = 1;
END IF;
END
spring jdbc code
SimpleJdbcCall jdbcCall = new SimpleJdbcCall(dataSource).withProcedureName(sp);
List<Map<String, Object>> list = (List<Map<String, Object>>) jdbcCall.execute(paramsArray).get("#result-set-1");
list get the result set with result set how can i get p_result with that.

Answer 1

I find it in simple way that i miss.
public Map<String, Object> xxx(String sp, Object... paramsArray) {
SimpleJdbcCall jdbcCall = new SimpleJdbcCall(dataSource).withProcedureName(sp);
return jdbcCall.execute(paramsArray);
}
execute() gives two parameters default
i.e.
1) #result-set-1
2) #update-count-1
#result-set-1 result set i.e. select record
and #update-count-1 returns update count. If we want to access result with select statement with out parameter. we just have to declare out parameter. execute() gives all the things in Map<String, Object> type.
So from map we can get all the multiple values that stored procedure returns.
For example my SP like
PROCEDURE xxx(
IN xxxxTINYINT(1) UNSIGNED,
IN xxxSMALLINT(2) UNSIGNED,
OUT p_isconfig BIT
)
BEGIN
SELECT....
SET p_isconfig = 1;
END
So in #result-set-1 i get select result.
and p_isconfig gives me result to. If you have any confusion then you can iterate map and identify that how get return parameters.
Iterator i = map.keySet().iterator();
while ( i.hasNext() ) {
String key = (String) i.next();
String value = params.get( key );
System.out.println("key: " + key + " --- value: " + value) ;
}
This way i found solution after reading many things. If any one have other option for this solution then please share with me.

You can try morejdbc (available in maven central) to call your procedure, it's more laconic and it's type safe:
import static org.morejdbc.SqlTypes.BIGINT;
import static org.morejdbc.NamedJdbcCall.call;
import org.morejdbc.*;
...
private JdbcTemplate jdbcTemplate;
...
Out<Integer> out = Out.of(INTEGER);
jdbcTemplate.execute(call("client_xxxx")
.in("p_xxxx", pValue)
.out("p_result", out));
System.out.println("Result is " + out.get());
For ref_cursor out parameter and Oracle database you can use
Out<List<Record>> out = Out.of(OracleSqlTypes.cursor((rs, idx) -> new Record(rs)));
jdbcTemplate.execute(call("client_xxxx")
.in("p_xxxx", pValue)
.out("p_result", out)); // will auto-close ref-cursor
System.out.println("Got result records: " + out.get());
