Running multiple hive queries using tHiveRow component in Talend
Your link reference shows a MySQL connection... this says nothing about the Hive JDBC driver capabilities, since running multiple statements in one JDBC statement is a driver specific feature!
To run multiple queries:Start with a tFixedFlowInput component. Configure one String column and choose table input option; you will get a table with one column. Each line, you add, will be one Hive statement. Now connect it with a tHiveRow component and use the column of the ingoing flow in the SQL textarea by <flowName>.<columnName> e.g.: row1.sqlStatement (if the String column in your tFixedFlowInput has the name "sqlStatement" and the connection between the tFixedFlowInput and the tHiveRow component is called "row1").
