+## Description
+
+
+## Syntax
+
+`VARCHAR ltrim_in(VARCHAR str[, VARCHAR rhs])`
+
+When there is no rhs parameter, remove the spaces that appear consecutively in
the parameter str starting from the left part; when there is an rhs parameter,
search and remove any characters in the rhs character set at the left end of
the string (regardless of order)
+
+## Examples
+
+```sql
+mysql> SELECT ltrim_in(' ab d') str;
++------+
+| str |
++------+
+| ab d |
++------+
+
+mysql> SELECT ltrim_in('ababccaab','ab') str;
