String functions

There are a number of string functions that can be used to alter strings. A description of a few of these functions are shown below:

  • The LOWER(fieldName) function changes the case of all characters in fieldName to lower case.
  • The INITCAP(fieldName) function changes the case of all characters in fieldName to proper case.
  • The LEFT(fieldName,N) function returns the left N characters of the string fieldName.
  • The SUBSTRING(fieldName from S for N) returns N characters starting from position S of the string fieldName. Note that both from S and for N are optional.
