with the contains operator, you can use a number of operators to define your search criteria. the following example enters a contains query against the news table to find all articles that contain the word oracle. the result is that when you use the catsearch operator to search a ctxcat index, query performance is generally faster for mixed queries. when documents arrive, you use the matches operator to classify each document a matches query finds all rows in a query table that match a given document. for example, to find all the rows in your text table that contain the word dog, enter a query specifying dog as your query term. for example, a query on the word this returns no hits when this is defined as a stopword. you can augment the knowledge base to define concepts and terms specific to your industry or query application. oracle text enables you to query on themes with the about operator. the text_query argument enables you to query words and phrases.
for example, if you enter a query of oracle and the system does not find this concept in the knowledge catalog, the system might use oracle as a related concept for look-up. for example, you can define a section for the
tag that enables you to query within this section using the within operator. the rewritten versions of the query are executed efficiently with a single call to contains or catsearch. when you use the multi-lexer to index a column containing documents in different languages, you can specify which language lexer to use during querying. use the about operator in english or french to query on a concept. for example, to retrieve all documents that are about politics, write your query as follows: logical operators such as and or or allow you to limit your search criteria in a number of ways. with store_sqe, you specify a name for the stored query expression and a query expression. to count the number of hits returned from a query with only a contains predicate, you can use ctx_query.count_hits in pl/sql or count(*) in a sql select statement. the definescore operator enables you to define how the score for a term or phrase is to be calculated.
query templates are an alternative to the existing query languages. rather than passing a query string to contains or catsearch , you pass a structured using self joins: example the following query uses a self join to return the name of each employee along with the name of the employee’s the following example shows a field section search against a ctxcat index using context grammar by means of a query template in a catsearch query., oracle queries for practice, oracle queries for practice, oracle contains query, oracle sql select statement examples, oracle query tutorial

the rest of this chapter describes the template class and the other classes you use to create dynamic source objects. a template creates a dynamicdefinition, which acts as a proxy for the sourcedefinition of the source produced by the template. you use a dynamicdefinition to get the source produced by a template. if you change the state of any one of the template objects that you used to create the final source, then the final source represents a result set that is different from that of the previous source. you pass in the sourcegenerator to the createdynamicdefinition method of the template to create a dynamicdefinition.
the template creates a dynamicdefinition that you use to get the source produced by the sourcegenerator for the template. to get the source produced by the generatesource method, you create a dynamicdefinition by passing the sourcegenerator to the createdynamicdefinition method of the template. the getcurrent method of a dynamicdefinition returns the sourcedefinition immutably associated with the source that the generatesource method currently returns. to the class, you add methods that get the current state of the template, set the values specified by the user, and then set the current state of the template. after you have stored the selections made by the end user in the metadatastate for the template, use the getsource method of the dynamicdefinition to get the dynamic source created by the template.

developed in java, sql developer runs on windows, linux and the mac os x. this is a great advantage to the increasing number of developers using alternative platforms. to install sql developer simply unzip the downloaded file. you can move to the adding objects to query builder topic. if you installed the sql developer icon on your desktop, click the icon to start your sql developer and move to step 4. if you do not have the icon located on your desktop, perform the following steps to create a shortcut to launch sql developer 3.0 from your desktop. in this section, you create a query based on the employees and departments tables.
drag and drop the departments table object over to the query builder window, so that the two table objects are displayed in the query builder window. in this topic, you sort the results using the sort type and sort order columns. note that these columns are added in the window below, in the order that you select them. as you work in the query builder window, your sql statement is built and is visible in the sql worksheet area. this is handy when you have multiple objects in the graphical view and you want to better organize them. the results of the query is displayed.
