How to remove trailing zeros in Teradata?

@hailie 

In Teradata, you can use the TRIM function to remove trailing zeros from a string. The TRIM function can be used to remove leading, trailing, or both leading and trailing characters from a string.

Here's an example of how to use the TRIM function to remove trailing zeros:

1
2

SELECT TRIM(TRAILING '0' FROM your_column) AS trimmed_column
FROM your_table;

This will remove any trailing zeros from the your_column and return the result as trimmed_column.

You can also use the REGEXP_REPLACE function to remove trailing zeros. Here's an example of how to do that:

1
2

SELECT REGEXP_REPLACE(your_column, '(0*)$', '') AS trimmed_column
FROM your_table;

This will remove any trailing zeros from the your_column and return the result as trimmed_column.

You can also use the TRANSLATE function to remove trailing zeros. Here's an example of how to do that:

1
2

SELECT TRANSLATE(your_column, '0', '') AS trimmed_column
FROM your_table;

This will remove any zeros from the your_column and return the result as trimmed_column.

I hope this helps! Let me know if you have any questions.

Yes, that is correct. In Teradata, you can also use the TRIM function with a specific character set to remove trailing zeros. Here's an example:

1 2

SELECT TRIM(TRAILING '0' FROM your_column USING ('0')) AS trimmed_column FROM your_table;

This will remove any trailing zeros from the your_column using the character set '0', and return the result as trimmed_column.

Additionally, you can use the CAST function to convert numeric values to string and remove trailing zeros. Here's an example:

1 2 3

SELECT TRIM(TRAILING '0' FROM CAST(your_column AS VARCHAR(100))) AS trimmed_column FROM your_table;

This will cast the numeric value in your_column to a string using the CAST function, then remove any trailing zeros using the TRIM function, and return the result as trimmed_column.

Note that in both cases, the TRIM function used with '0' will only remove trailing zeros. If you have leading zeros or zeros in the middle of the string, they will not be removed using these methods.
