SyntaxRemarksexpressionLike “pattern”
The Like operator syntax has these parts:
Part
Description
expression
SQL expression used in a WHERE clause .
pattern
String or character string literal against which expression is compared.
You can use the Like operator to find values in a field that match the pattern you specify. For pattern, you can specify the complete value (for example,
Like “Smith”), or you can use wildcard characters to find a range of values (for example,Like “Sm*”).In an expression, you can use the Like operator to compare a field value to a string expression. For example, if you enter
Like “C*”in an SQL query, the query returns all field values beginning with the letter C. In a parameter query, you can prompt the user for a pattern to search for.The following example returns data that begins with the letter P followed by any letter between A and F and three digits:
Like “P[A-F]###”The following table shows how you can use Like to test expressions for different patterns.
