+### LTRIM{#ltrim}
+
+Removes leading characters from a `string`. If no `character` is specified for trimming, space is used.
+
+#### Syntax
+
+The syntax is as follows:
+
+```sql
+LTRIM ( expression [, character ] )
+```
+
+##### expression
+
+`expression` is any string expression to be trimmed. If `expression` is `NULL`, the function will return `NULL`.
+
+##### character
+
+`character` is an optional single character string expression containing the character to trim. If omitted, the space character is used instead.
+
+{{% alert color="info" %}}
+Only a single character is supported. `character` parameters with more than one character may not work in all supported databases.
+{{% /alert %}}
+
+#### Examples
+
+```sql
+SELECT LTRIM(LastName, 'D') FROM Sales.Order WHERE Price = 1.50000001
+```
