Saving a ddl file in Oracle SQL Developer. In the context of SQL, data definition or data description language (DDL) is a syntax for creating and modifying database objects such as tables, indices, and users. DDL statements are similar to a computer programming language for defining data structures, especially database schemas.
The index of the found name is then used to look up the ordinal in the Export Ordinal table. In 16-bit Windows, the name table was not sorted, so the name lookup overhead was much more noticeable. It is also possible to bind an executable to a specific version of a DLL, that is, to resolve the addresses of imported functions at compile-time.
The Actian NoSQL Database enables developers using object oriented languages to transactionally store their information by allowing the respective language to act as the Data Definition Language (DDL) for the database. In other words, the memory model is the database schema model. [4]
If the data access layer supports multiple database types, the application becomes able to use whatever databases the DAL can talk to. In either circumstance, having a data access layer provides a centralized location for all calls into the database, and thus makes it easier to port the application to other database systems (assuming that 100% ...
User-defined types (UDTs) that allow users to create simple or complex data types which can be serialized and deserialized within the database. The SQL CLR relies on the creation, deployment, and registration of CLI assemblies, which are physically stored in managed code dynamic load libraries (DLLs). These assemblies may contain CLI namespaces ...
A view is defined by giving a name to such an expression, such that the name can subsequently be used as a variable name. (Note that the expression must then mention at least one base relation variable.) By using a Data Definition Language (DDL), it is able to define base relation variables. In SQL, CREATE TABLE syntax is used to define base ...
The Table<T> encapsulates the data in the table, and implements the IQueryable<T> interface, so that the expression tree is created, which the LINQ to SQL provider handles. It converts the query into T-SQL and retrieves the result set from the database server. Since the processing happens at the database server, local methods, which are not ...
db4o build name format is meant to provide all the necessary information about the version, time of build and supported platform: For example: db4o-7.2.30.9165-java.zip db4o – name of the product, i.e. db4o database engine 7.2 – the release number 30 – iteration number, i.e. a sequential number identifying a development week
