Query Editor in Interactive SQL

The Query Editor is a tool in Interactive SQL that helps you build SELECT statements. You can create SQL queries in the Query Editor, or you can import queries and edit them. When you have finished your query, click OK to export it back into Sybase Central or Interactive SQL for processing.

Using SQL statements with the Query Editor

You do not need to use SQL statements to create queries with the Query Editor. However, you can use SQL statements with the Query Editor in the following ways:

You can create a query in the SQL Statements pane in Interactive SQL, and import it into the Query Editor by highlighting the code before you open the editor.
At any time while using the Query Editor, you can click SQL at the bottom of the window to see the SQL statements for the query you are building. You can directly edit the code, and the fields are automatically updated in the Query Editor.

Configuring the Query Editor

You can configure the Query Editor from Interactive SQL or Sybase Central so that the SQL is fully formed, meaning that all table and column names are fully qualified and names are quoted. This extra formatting is not normally necessary, but it ensures that the SQL works in all situations. You can also choose to get a list of tables on startup.

To configure the Query Editor from Interactive SQL click Tools » Options » SQL Anywhere, » Query Editor tab.

Query Editor tabs

The Query Editor provides a series of tabs that guide you through the components of a SQL query, most of which are optional. The tabs are presented in the order that SQL queries are usually built:

Tab	Description
Tables tab	Use this tab to specify the tables in your query.
Joins tab	Use this tab to specify a join strategy for combining the data in the tables if you include more than one table in your query. If you do not specify a join strategy, then the Query Editor suggests one. If there is a foreign key relationship between the tables, it generates a join condition based on that relationship, or it suggests a cross product. When you open queries, the Query Editor accepts exactly the join strategy that you specified (and an unspecified JOIN is not defaulted to KEY JOIN, as it would be otherwise in SQL Anywhere).
Columns tab	Use this tab to specify the columns in your result set. If you do not specify columns, all columns appear.
INTO tab	Use this tab to assign results to variables.
WHERE tab	Use this tab to specify conditions for restricting the rows in your result set.
GROUP BY tab	Use this tab to group rows in the result set.
HAVING tab	Use this tab to restrict the rows in your result set based on group values.
ORDER BY tab	Use this tab to sort the rows.

Query Editor tools

The Query Editor also contains the following tools:

Window	Description
Expression Editor	Use the Expression Editor to build search conditions or define computed columns. See Expression Editor in Interactive SQL.
Derived Table	Use this window, which is nearly identical to the main Query Editor, to create derived tables and subqueries.

Each component of the Query Editor has context-sensitive online help that describes how to use the tabs, and provides links into the SQL Anywhere documentation that explains relevant concepts and usage.
