SQL putting text in query output, For that, it is better to include some user defined columns from the outside at runtime. These columns are valid only for this output. These included E.g query would look like this (without adding that extra column that will say what is type of error, because, i don't know is it possible to do that) SELECT id,aa,bb,NULL AS cc, NULL AS dd FROM test WHERE aa=SomeRequirement AND bb=SomeRequirement UNION ALL SELECT id,NULL,NULL,cc,dd FROM test2 WHERE cc=SomeRequirement AND dd=SomeRequirement
If you are using MYSql, you can use the
concat() as :
update tableName set columnName= CONCAT('www.mypizza.com/', columnName);

update tableName set "columnName"='www.mypizza.com/'||"columnName";
In SQL Server you can use
+ for string concatenation as:
update tableName set name='www.mypizza.com/'+columnName;

This is the same as the Text data type. Whatever text could hold, this can hold, so you don't need to worry about running out of room by switching to VARCHAR(MAX).
You mean like this?:
SELECT 'www.mypizza.com/' + ColumnName AS ColumnName FROM TableName
Depending on the rest of your application environment, there is likely a much better way to accomplish this. But in terms of just using SQL to add static text to a column in a SELECT statement, you can just concatenate the text directly in the statement.
Or, if you wanted to UPDATE the column values, something like this:
UPDATE TableName SET ColumnName = 'www.mypizza.com/' + ColumnName
Same principle, just using an
UPDATE instead of a
SELECT, which will modify the underlying data instead of just modifying the view of the data.
