The following articles describe how to develop an Oracle stored procedure, including how to run a stored procedure and how to run the relevant code in a stored procedure, the following
The execution permission of oracle stored procedures is an essential tool in the database system. stored procedures are a set of SQL statements pre-compiled to implement a complex function. I will not talk about its advantages. Let's talk about the problems I encountered. During project development, I need to use a stored
Recently, I used java to verify the metadata of an excel form. The data size is very large and the verification rules are complicated. If you simply use the program for verification, the efficiency will be very low, considering that the oracle stored procedure can be compiled, the data will be put into the cache after each compilation, and the next retrieval will
What is a stored procedure.
is a collection of SQL that can be manipulated programmatically.
the advantages of stored procedures. execution is efficient because the stored procedure is precompiled, that is, when the compile is created, and the SQL statement is executed on

Here is a summary of three popular database tutorials on how to use PHP tutorials to invoke their stored procedures, we have a MySQL tutorial, Oracle,mssql server Oh.
function Check_login ($user, $pass) {$conn = Ocilogon (' user ', ' Pass ', ' database ');$sql = ' Begin:result: = Test.check_login (: User,:p); end; ';$stmt = Oci_parse ($conn, $sql);$result = ";Oci_bind_by_name ($stmt, ': User ',
means to specify the parameter name when calling the subroutine and use the correlated symbol "=>" to provide corresponding values or variables for it. When using this method, you do not need to consider the positional relationship. Example:
exec add_dept(loc=>'NEW YORK',dno=>50); exec add_dept(loc=>'NEW YORK',dname=>'SALES',dno=>60)
4.3 Combined Transfer
Combined Transfer refers to the use of location transfer and name transfer when calling a subroutine. The example is as follows:
exec add
cursor:FETCH:Product_cursor;INTOId, name, price; // store the value in the three variables declared above.// If the cursor returns a result that may contain many rows, each row of data will be retrieved cyclically,You can use product_cursor % NOTFOUND to determine when the illusion ends.
Step 5: Close the cursor:CLOSE product_cursor;12. Execute the stored procedure in the Command windowCommand: exec
1. The following describes the Oracle stored procedure! 2. Focus on the preparation, debugging, and application of stored procedures, rather than the introduction of too many syntaxes! 3. As long as you understand SQL statements, you can continue

anonymous stored procedure and run it in PL/SQL. Since the statement passed. This indicates that this statement is correct and the problem occurs during the stored procedure.

Basic oracle
Previously, I used C # to connect to the SQL Server database. Recently, due to work requirements, you need to use C # to connect to the Oracle database and operate the data in the database through the stored procedure to implement the function of adding, deleting, modifying, and querying data (with paging function. In addition, to facilitate database expansion in

Oracle is always different for advanced features (I hate this, if it's a product that needs to be programmed specifically for this product, and that's why I never looked at a platform like WebLogic), the big object access is set to use its own LOB objects, but luckily I can still pass long Raw to replace. So that the program does not need a specific encoding. But for the stored
