It is a way to modify an SQL Insert Script with SED Command in order to insert word DATE before date value?
Yes, you can use the sed
command to modify an SQL insert script and insert the word "DATE" before a date value. Here's an example of how you can accomplish this:
Let's assume you have an SQL insert script with a line that inserts a date value:
sqlINSERT INTO table_name (column1, column2, date_column) VALUES ('value1', 'value2', '2023-05-31');
To insert the word "DATE" before the date value, you can use the sed
command with a regular expression to match the date format and replace it with "DATE 'date_value'". Here's the sed
command you can use:
bashsed "s/'[0-9]\{4\}-[0-9]\{2\}-[0-9]\{2\}'/DATE '&'/g" input.sql > output.sql
Let's break down the sed
command:
s/
starts the substitution command.'[0-9]\{4\}-[0-9]\{2\}-[0-9]\{2\}'
is the regular expression to match the date format (YYYY-MM-DD). Adjust the regular expression if your date format differs.DATE '&'
is the replacement string.&
represents the matched pattern./g
at the end of the command performs the substitution globally on each occurrence in the line.input.sql
is the input SQL file with the original insert script.output.sql
is the output file where the modified script will be saved.
After running the sed
command, the output.sql file will contain the modified insert script with "DATE" inserted before the date value:
sqlINSERT INTO table_name (column1, column2, date_column) VALUES ('value1', 'value2', DATE '2023-05-31');
Please note that the sed
command performs text-based pattern matching and substitution. It is important to ensure the pattern matches the date format in your SQL insert script accurately. Adjust the regular expression as needed to match your specific date format.
