declare

NAME
      declare - define or print variables

SYNOPSIS
      declare [ATTRIBUTE_OPTION...] [-p] [NAME[=VALUE]...]

DESCRIPTION
      Declare variables and/or give them attributes. If no NAMEs are given then display the values of variables. The -p option will display the attributes and values of each NAME.
      When -p is used with NAME arguments, additional options are ignored. When -p is supplied without NAME arguments, it will display the attributes and values of all variables 
      having the attributes specified by the additional options. If no other options are supplied with -p, declare will display the attributes and values of all shell variables.

      Please refer to the Variables section for the list of pre-set variables.

ATTRIBUTE OPTIONS
      -x
      Mark NAMEs for export to subsequent commands via the environment.

      Using '+' instead of '-' turns off the attribute instead. If both '+' and '-' are specified for the same attribute, that attribute is turned off.

OPTIONS
      -p VARIABLE
      Prints the value of a variable.

EXAMPLES
      Let us first declare a variable using the declare command

declare myvar="This is FluidShell"

 
      To change the default prompt in FluidShell, use the below command:

declare prompt=$

      To enable variable substitution in SQL statements, use the following command:

declare sql_variable=1

      To declare the number of statements to be kept in memory:

declare histsize=250

      To declare the number of results declares returned by a query:

declare max_rows=100

 
      To display the SQL Statements in the console, when queries are executed, use the command:

declare options.console.show.sql=true

      To display column headers with SQL results:

declare options.console.show.columnheaders=true

      To declare the SQL results to be displayed as Form Results:

declare options.console.show.resultasform=true

      To declare the Margin character length with SQL results:

declare options.console.show.margincharlength=5

      To display warnings with SQL queries:

declare options.console.show.warnings=true

      To display warnings headers with SQL queries:

declare options.console.show.warningheaders=true

      A variable can be removed using unset command.
