Printing integer variable and string on same line in SQL

Question

declare @x INT = 1 /* Declares an integer variable named "x" with the value of 1 */
    
PRINT 'There are ' + CAST(@x AS VARCHAR) + ' alias combinations did not match a record' /* Prints a string concatenated with x casted as a varchar */

Numbers have higher precedence than strings so of course the + operators want to convert your strings into numbers before adding.

You could do:

print 'There are ' + CONVERT(varchar(10),@Number) +
      ' alias combinations did not match a record'

or use the (rather limited) formatting facilities of RAISERROR:

RAISERROR('There are %i alias combinations did not match a record',10,1,@Number)
WITH NOWAIT

You can't combine a character string and numeric string. You need to convert the number to a string using either CONVERT or CAST.

For example:

print 'There are ' + cast(@Number as varchar) + ' alias combinations did not match a record'

or

print 'There are ' + convert(varchar,@Number) + ' alias combinations did not match a record'

Double check if you have set and initial value for int and decimal values to be printed.

This sample is printing an empty line

declare @Number INT
print 'The number is : ' + CONVERT(VARCHAR, @Number)

And this sample is printing -> The number is : 1

declare @Number INT = 1
print 'The number is : ' + CONVERT(VARCHAR, @Number)

You may try this one,

declare @Number INT = 5                            
print 'There are ' + CONVERT(VARCHAR, @Number) + ' alias combinations did not match a record'

If you don't want to manually cast types, you can use the CONCAT-function for this.

PRINT CONCAT('There are ', @Number, ' alias combinations did not match a record')
