An sql:query element in the stylesheet.
For example:
<sql:query column="{$column}" table="{$table}" where="{$where}" xsl:extension-element-prefixes="sql"/ >(result with HTML-table-output)
<sql:query column="{$column}" table="{$table}" where="{$where}" row-tag="TR" column-tag="TD" separatorType="tag" xsl:extension-element-prefixes="sql"/ >

prepareAttributes
Description copied from class:StyleElement
Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass- Specified by:
prepareAttributes
in classStyleElement
- Throws:
XPathException
- if a static error is detected
-
validate
Description copied from class:StyleElement
Check that the stylesheet element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.- Overrides:
validate
in classStyleElement
- Parameters:
decl
- the declaration to be validated- Throws:
XPathException
- if any error is found during validation
-
compile
Description copied from class:StyleElement
Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.- Overrides:
compile
in classStyleElement
- Parameters:
exec
- the Executabledecl
- the containing top-level declaration, for example xsl:function or xsl:template- Returns:
- either a ComputedExpression, or null. The value null is returned when compiling an instruction that returns a no-op, or when compiling a top-level object such as an xsl:template that compiles into something other than an instruction.
- Throws:
XPathException
- if validation fails
-
