How do I protect my site from SQL injection when I'm getting? Description = value

from url

and searching the object in the XML column in the database with the specified value?

Here is the sample code: 

  from sqlQuery = string.format (@ [data] "+ schema + @". [MyOBjects] WHERE " Data.exist ('/ data ["value" = \ "{0} \"]') = 1 "+", property, value);   
 Thanks for any help   
 
 
 about the following View the article to protect your code from SQL injection:  
 In your case, you want to use parameterized queries. Checkout "Step 3. Use Parameters with dynamic SQL".  
 You can do anything like this:  
  string connection string = "..."; String schema = "..."; String value = "..."; (SqlConnection connection = New SqlConnection (connectionString)) {string sql = string.format ("Select [data] FROM {0}. [MyOBjects] WHERE data.exist ('/ data [\" theValue \ "= sql: variable ( \ "@value \ @ Value ", System.Data.SqlDbType.NVarChar, 255) {value = value}); ....}

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
