| *? PL Help |
| * Expand PL variables from now on. |
| (this is also implied by all the following). |
| * VARNAME = Variable value Set variable value |
| * VARNAME = Unset variable |
| * VARNAME ~ Set variable value to the value of the very |
| next SQL value or count fetched (see details |
| at the bottom of this listing). |
| * VARNAME _ Same as * VARNAME _, except the query is |
| done silently (i.e, no rows to screen) |
| * break [foreach|if|while|file] Exits a PL block or file early |
| * continue [foreach|while] Exits a PL block iteration early |
| * dump VARNAME path.txt Dump variable value to text file |
| * end foreach|if|while Ends a PL block |
| * foreach VARNAME ([val1...]) Repeat the following PL block with the |
| variable set to each value in turn. |
| * if (logical expr) Execute following PL block only if expr true |
| * list[values] [VARNAME1...] List PL variable(s) (defaults to all) |
| * listsysprops [VARNAME1...] List Java System property(s) (defaults to all) |
| * load VARNAME path.txt Load variable value from text file |
| * prepare VARNAME Use ? in next SQL statement to upload val. |
| (Just "?", "*{?}" would mean the auto var.). |
| * while (logical expr) Repeat following PL block while expr true |
| |
| Use PL variable values (which have been set) like: *{VARNAME}. |
| Use System Property values (which you may not set) like: ${property.name}. |
| You may use /VARNAME instead iff /VARNAME is the first word of a SQL command. |
| Use PL variables in logical expressions, like (*VARNAME == 1). |
| Auto. variable ? is set to the very next SQL datum fetched (or update count). |
| Query: The value of the first field of the first row returned. |
| other: Return status of the command (for updates this will be |
| the number of rows updated). |
| '* VARNAME ~' or '* VARNAME _' sets the specified variable's value exactly |
| like ?. (~ will echo the value, _ will do it silently). |
