The previous section discussed SQL*Plus variables, which are variables maintained by the tool SQL*Plus. The SQL*Plus client-side program replaces all variables with actual values before the SQL commands are sent to the Oracle DBMS. This section discusses bind variables, an important component of the SQL language. To be more precise, bind variables are a component of dynamic SQL, a PL/SQL interface that allows you to build and process SQL statements at runtime. Bind variables are tool-independent. Bind variables are extremely important if you want to develop database applications for critical information systems. Suppose you have a database application to retrieve employee details. Application users just enter an employee number in a field on their screen, and then click the Execute button. For example, these SQL statements could be generated for two different database users, or for the same user using the same application twice: c# ocr image to text freeCreating Optical Character Recognition (OCR) applications using Neural Networks[^] A C# Project in Optical Character Recognition (OCR) ... ocr sdk for c#.net The C# OCR Library | Iron Ocr - Iron Software

Tesseract : Tesseract is probably the most accurate open source OCR engine available. SQL> select * from employees where empno = 7566; SQL> select * from employees where empno = 7900; These two SQL statements are obviously different, and the Oracle DBMS will also treat them as such. The optimizer will optimize them separately, and they will occupy their own memory structures (cursors). This approach can easily flood your internal memory, and it also forces the optimizer to produce execution plans over and over again. A much better approach would be to use a bind variable in the SQL command, instead of the literal employee number, and to provide values for the bind variable separately. In other words, all SQL commands coming from the application look like the following: SQL> select * from employees where empno = :x; Now, the Oracle DBMS is able to use cursor sharing, the optimizer can produce a single execution plan, and the SQL command can be executed many times for different values of the bind variable. SQL*Plus offers support for bind variables with the VARIABLE and PRINTcommands. You will also use the SQL*Plus EXECUTE command, allowing you to execute a single PL/SQL statement. Does C code initialize strings to NULLs to avoid endless strings Does C code use strncpy() rather than strcpy() And strncat() and strncmp() Does the program use additional boolean variables to document conditional tests Does the program use additional boolean variables to simplify conditional tests 9 You can declare bind variables with the SQL*Plus VARIABLE command, and you can display bind variable values with the SQL*Plus PRINT command. Because SQL doesn t support any syntax to assign values to bind variables, we use the SQL*Plus EXECUTE command to execute a single PL/SQL command from SQL*Plus. Listing 11-16 shows examples of using these commands. Listing 11-16. Declaring Bind Variables and Assigning Values SQL> variable x number SQL> variable y varchar2(8) SQL> execute :x := 7566 PL/SQL procedure successfully completed.
