Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance SQL database in Microsoft Fabric

\ breaks a long string constant, character or binary, into two or more lines for readability.

Syntax

syntaxsql

<first section of string> \  
<continued section of string>

Arguments

<first section of string>
Is the start of a string.

<continued section of string>
Is the continuation of a string.

Remarks

This command returns the first and continued sections of the string as one string, without the backslash. The new line after the backslash must either be a line feed character (U+000A) or a combination of carriage return (U+000D) and line feed (U+000A) in that order.

Examples

B. Splitting a binary string
