Zen TablesThe following table lists XML special characters that cause problems when they appear in sql strings, and the XML entitiesto substitute for them.Table 1–1: XML Entities for Use in sql Attribute ValuesCharacter>
Data SourcesAttributewhereClauseDescriptionAn SQL WHERE clause such as "Name='Elvis'".When a whereClause is provided in the definition in XData Contents, this setsan initial value for the whereClause property of the tablePane object. If client-side or serversidecode later changes the value of this whereClause property, the new value overrides theoriginal value. This means you can initially set up a table to show only certain values, butanother line of code can change the whereClause value, causing your users to see a differentset of values when it refreshes.For example, if any column filters are defined in this table, Zen dynamically creates aWHERE clause for the based on the current filter values selected by the user.The whereClause value can be a literal string, or it can contain a Zen #()# runtimeexpression.To have the generate an SQL query, you must do the following:1. Provide a value for the tableName attribute.2. Do not provide values for the sql, queryClass, queryName, or OnCreateResultSet. All of these attributes take precedenceover the behavior described in this topic.After you satisfy the first two conditions, Zen assumes a "columns" value for dataSource.3. Define the names of one or more columns by providing elements inside the . There must be atleast one column defined or a “Missing SELECT list” error will result.4. You can add query parameters by providing elements inside the .5. You can add clauses for the generated query by providing the attributes groupByClause, orderByClause,or whereClause, or by allowing defaults to prevail as described in the table above.The following is a simple example:This example generates an SQL statement similar to the following:SELECT ID,Name FROM MyApp.EmployeeZen executes this query to provide the contents of the table. In the example, the ID column is marked as hidden. This meansthat its value is fetched (it can be used for conditions or actions) but not displayed. For details about hidden and other attributes, see the section “Table Columns.”Note:A generated SQL query can be useful for tables with column filters.1.2.3 Referencing a Class QueryA can reference a pre-existing class query to obtain a %ResultSet object. The following attributes support thisapproach: , , , , and .Using Zen Components 7
