This article explain how to use oracle functions while inserting/Updating data using tOracleOutput.
Let us take a simple example
Now if we would like to use Oracle function UPPER and TO_TIMESTAMP_TZ while inserting data in table.
We could do this using "Additional Column" Setting in tOracleOutput .
Normally "Additional Column" Setting does not have access to resultset of Main flow. So we cannot use expression like row2.name or row2.dob_tz.
it can access the globalMap so expression like ((String)globalMap.get("name")) or ((String)globalMap.get("row2.dob_tz")) are good to go.
As per Talend workflow design, in a Subjob , tOracleOutput will be configured 1st then rest of flow , so if we try to set the global Variable during the main flow , "tOracleOutput - Additional Column" cannot access updated globaMap Variable info
So , thanks to iterator of tFlowToIterate , we can create iterate over globalMap Variables of main flow. So job look like this.
tOracleOutput - Additional Column
name --> "UPPER('" + ((String)globalMap.get("row2.name")) + "')"
dob_tz --> "TO_TIMESTAMP_TZ('" + ((String)globalMap.get("row2.DOB_TZ")) + "','YYYY-MM-DDHH:MISTZH:TZM')"
Output in Database
Thanks for the article.
