Replacing valuses containig space and special characters
**Extremely sorry for the typos in heading

Old:
Code:
CAST ('${DEFAULT_HIGH_DATE}' AS DATE FORMAT 'YYYY-MM-DD')

New :
Code:
CAST(CAST('${G_DEFAULT_HIGH_DATE}' AS DATE FORMAT 'MM-DD-YYYY') as DATE FORMAT 'YYYY-MM-DD')

Need to change old format as new format

cat file1
Code:
CAST ('${DEFAULT_HIGH_DATE}' AS DATE FORMAT 'YYYY-MM-DD')


Code:
 
awk {gsub(CAST \(\'\$\{EDW\_DEFAULT\_HIGH\_DATE\}\' AS DATE FORMAT \'YYYY\-MM\-DD\'\),
"CAST\\(CAST\\(\\'\\$\\{GLODB\\_\\TD\\_EDW\\_DEFAULT\\_HIGH_DATE\\}\\'" "AS" "DATE" "FORMAT \\'MM\\-\\DD\\-YYYY\\'\\)" "as" "DATE" "FORMAT" "\\'YYYY\\-MM\\-DD\\'\\)" ;print}' file1

This seems to be just a replace issue easily handled by sed without the need for the power of awk.

The $ is the only character that needs to be quoted to prevent the system thinking a variable is in use, this works...

Code:
sed -e "s/CAST ('\${DEFAULT_HIGH_DATE}' AS DATE FORMAT 'YYYY-MM-DD')/CAST(CAST('\${G_DEFAULT_HIGH_DATE}' AS DATE FORMAT 'MM-DD-YYYY') as DATE FORMAT 'YYYY-MM-DD')/g" x.x

where x.x is file containing
Code:
CAST ('${DEFAULT_HIGH_DATE}' AS DATE FORMAT 'YYYY-MM-DD')
