|
|---|
| 49 | The QSqlSelectCursor class provides browsing of general SQL
|
|---|
| 50 | SELECT statements.
|
|---|
| 51 | <p>
|
|---|
| 52 |
|
|---|
| 53 | <p> QSqlSelectCursor is a convenience class that makes it possible to
|
|---|
| 54 | display result sets from general SQL <tt>SELECT</tt> statements in
|
|---|
| 55 | data-aware Qt widgets. QSqlSelectCursor is read-only and does not
|
|---|
| 56 | support <tt>INSERT</tt>, <tt>UPDATE</tt> or <tt>DELETE</tt> operations.
|
|---|
| 57 | <p> Pass the query in at construction time, or use the
|
|---|
| 58 | <a href="qsqlquery.html#exec">QSqlSelectCursor::exec</a>() function.
|
|---|
| 59 | <p> Example:
|
|---|
| 60 | <pre>
|
|---|
| 61 | ...
|
|---|
| 62 | QSqlSelectCursor* cur = new QSqlSelectCursor( "SELECT id, firstname, lastname FROM author" );
|
|---|
| 63 | <a href="qdatatable.html">QDataTable</a>* table = new <a href="qdatatable.html">QDataTable</a>( this );
|
|---|
| 64 | table-><a href="qdatatable.html#setSqlCursor">setSqlCursor</a>( cur, TRUE, TRUE );
|
|---|
| 65 | table-><a href="qdatatable.html#refresh">refresh</a>();
|
|---|
| 66 | ...
|
|---|
| 67 | cur-><a href="qsqlquery.html#exec">exec</a>( "SELECT * FROM books" );
|
|---|
| 68 | table-><a href="qdatatable.html#refresh">refresh</a>();
|
|---|
| 69 | ...
|
