These methods take as input a String parameter name or int parameter index as well as an oracle. You get the contents of the nested table by using the next method and the appropriate getagray XXX method. ARRAY attribute for this purpose.
AWS Developer Forums: SQL Workbench error with getArray
ARRAY Automatic Indexing If an array is in auto-indexing mode, then the array object maintains an index table to hasten array element access. Array object z object. The database stores a nested table in a separate table which has a single column, and the type of that column is a built-in type implememted an object type.
Use the Oracle specific method createArray of oracle.
Retrieving Elements of a Structured Object Array According to a Type Map By default, if you are working with an array whose elements are structured objects, and you use getArray or getResultSetthen the Oracle objects in the array will be mapped to their corresponding Java data types according to the default mapping.
Apparently soI must have missed the “in the current row” part when I was reading about the method!
Use getOracleArray to return an oracle. Nov 27, 2: SQL Workbench error with getArray. The return type of the getArray method is java. The elements are of the oracle. As previously described, you can specify a type map or use the default type map for your connection to convert to Java types.
To create a single-level collection, the elements are a one dimensional Java array, while to create a multilevel collection, the elements can be either an array of oracle. The MutableArray class has an oracle. Custom collection classes generated by JPublisher offer all the functionality described earlier in this chapter, as well as the following advantages:.
Retrieving Array Elements into an oracle.
Using Array Objects
Note that if you use getResultSet to obtain the array, then you must would first get the result set object, and then use the next method to iterate through it.

Foe you do not want to use the default type map of the connection, another version of the method, getResultSet mapenables you to specify an alternate type map. Retrieves the value of the designated column in the current row of this ResultSet object as an Array object in the Java programming language.
Jira Software Support
The following topics are covered: The JDBC drivers extend these methods to support multilevel collections. Oracle also provides a getOracleArray indexcount method getarfay get a subset of the array elements.
The following topics are discussed: Oracle supports only named collections, where you specify a SQL type name to describe a type of collection. Typically it will directly or indirectly include an oracle. The getArray method returns a Java array that holds the collection elements. ARRAY class, which is weakly typed, or materializing it as an instance of a custom Java implementwd that you have created in advance, which is strongly typed.
The same createArray factory method you use jsbc create single-level collections, can be used to create multilevel collections as well.
