How to use ApplyMap & RENAME for GUID Field names to readable ones?

[b_garside]

I have a Table that's stores questions identified with GUID's instead of the literal questions names I need to translate them using ApplyMap and RENAME

The problem I'm having is how do I translate field names to readable values. I dont know how to map field names to something else.

the manual way to do this would be to alias all the fields....

Mapping_Questions:
Mapping LOAD frmqstnQuestionText,
frmqstnGUID;
SQL SELECT frmqstnQuestionText,
frmqstnName
FROM "master".dbo."QV_QuestionNames";

Form_6248:
LOAD prjrptId,
prjrptProjectId as ProjectID,
prjrptFormId,
prjrptReportID,
prjrptDate,

"Qcabd5f36_9b83_46b8_a510_57921949b40b",
"Q0a3bbcfd_456b_414c_93bc_64a65a3aa880",

"Q95e48c02_3bf0_4b78_abc4_8b7708a2720";
SQL SELECT prjrptId,
prjrptProjectId,
prjrptFormId,
prjrptReportID,
prjrptDate,
  "Qcabd5f36_9b83_46b8_a510_57921949b40b",
  "Q0a3bbcfd_456b_414c_93bc_64a65a3aa880",

FROM "master".dbo."vw_6248";

If the mapping tables contains the guids and the names to replace them with then add a line at the end of the script:

Mapping_Questions:
Mapping SQL SELECT frmqstnGUID,frmqstnQuestionText
FROM "master".dbo."QV_QuestionNames";

...other stuff

rename fields using Mapping_Questions;

For soem reason its not working does this look correct?

Table view

Mapping_Questions:
MAPPING SQL SELECT
frmqstnName, //Dirty
frmqstnQuestionText     //Clean
FROM "master".dbo."QV_QuestionNames";

Form_6248:
LOAD prjrptId,
prjrptProjectId as ProjectID,
prjrptFormId,
prjrptReportID,
prjrptDate,
"Qcabd5f36_9b83_46b8_a510_57921949b40b",

Rename fields using Mapping_Questions;

[b_garside]

Maybe I need to get rid of the Preceding load for the renaming to take effect?

[Gysbert_Wassenaar]

In the table view image the guids contain hyphens, not underscore characters. Make sure you use the exact same case sensitive field names.

[b_garside]

Ok, duh, I should have picked up on that. So I will use

a string fucntion Replace(s, fromstring ,tostring)  to fix the _ to - hyphens ?

[b_garside]

Thank you so much!

[rustyfishbones]

The Mapping Load Table must be the first sheet in the Script Editor

[b_garside]

ok, so now I have that part working.

How do I prevent the other non GUID fields from being renamed or destroyed when it doesn't find a match ?
