| /** returns the query previously set at the analyzer, with all application-level |
| features being substituted by their database-level counterparts. |
| |
| <p>The <type>XSingleSelectQueryAnalyzer</type> is an application-level component, |
| which in some respect understands SQL features usually not present at the database |
| level. As a prominent example, you might pass a <code>SELECT</code> statement to the analyzer |
| which is based on another query.</p> |
| |
| <p>While all other methods will handle those additional features transparently - e.g. |
| the query in the <code>FROM</code> part of a <code>SELECT</code> statement will be handled |
| as if it really is a table -, <code>getQueryWithSubstitution</code> gives you the SQL statement |
| where all those features have been stripped, and replaced with appropriate standard SQL.</p> |
| |
| <p>For example, consider a database document which contains a client-side query named <code>All Orders</code>. |
| This query is not known to the underlying database, so an SQL statement like |
| <code>SELECT * from "All Orders"</code> would be rejected by the database. However, instantiating |
| a <type>SingleSelectQueryAnalyzer</type> at the <type>Connection</type> object, and passing it the above query, |
| you can then use <code>getQueryWithSubstitution</code> to retrieve a statement where <code>"All Orders"</code> |
| has been replaced with the <code>SELECT</code> statement which actually constitutes the <code>"All Orders"</code> |
| query.</p> |
| |
| @throws com::sun::star::sdbc::SQLException |
| if the query represented cannot be completely substituted. A usual case for this is a recursion in |
| the sub queries: Consider a query named <code>foo</code>, which is defined as <code>SELECT * FROM "bar"</code>. |
| Now assume that <code>bar</code> is a query defined as <code>SELECT * FROM "foo"</code>. Passing either |
| of those statements to an analyzer, and calling <member>getQueryWithSubstitution</member>, would result |
| in an exception being thrown, since it's impossible to substitute the sub queries with their |
| constituting statements. |
