am using this connection string to connect to mysql from java:
jdbc:mysql://localhost:3306/db?noDatetimeStringSync=true&useUnicode=yes&characterEncoding=UTF-8
is it possible to set the session variable in the string so that SET UNIQUE_CHECKS=0; would be executed upon connecting to server? the obvious
jdbc:mysql://localhost:3306/db?noDatetimeStringSync=true&useUnicode=yes&characterEncoding=UTF-8&unique_checks=0
doesn't seem to work, based on the fact that
'jdbc:mysql://localhost:3306/db?noDatetimeStringSync=true&useUnicode=yes&characterEncoding=UTF-8&unique_checks=blahblah`
doesn't generate any error.
Cheers!
How about using sessionVariables:
jdbc:mysql://localhost:3306/db?noDatetimeStringSync=true&useUnicode=yes&characterEncoding=UTF-8&sessionVariables=unique_checks=0
Your question is thus more "How do I concat Strings in Java?" ?
If so, then just use the + operator:
int uniqueChecks = 0; // Assign session variable here.
String url = "jdbc:mysql://localhost:3306/db?unique_checks=" + uniqueChecks;
Alternatively you can also use String#format() wherein you can use the %d pattern to represent a decimal:
int uniqueChecks = 0; // Assign session variable here.
String url = String.format("jdbc:mysql://localhost:3306/db?unique_checks=%d", uniqueChecks);
You can use Statement.execute() to run pretty much every statement the DB understands, including such a SET-statement.
The advantage of using an URL parameter or a dedicated method is that the JDBC-driver is actually aware that the option was set and can react accordingly. This may or may not be useful or necessary for this particular option, but it's vital for other options (for example toggling autocommit with such a statement is a very bad idea).
BalusC, thanks for a reply! actually I need to do that in Talend etl tool(which itself is a java code generator) and the only line i can edit is the "jdbc:mysql://localhost:3306/db?noDatetimeStringSync=true&useUnicode=yes&characterEncoding=UTF-8" string, which gets translated to this java code:
String url_tMysqlBulkExec_1 = "jdbc:mysql://"
+ "localhost" +
":"
+ "3306"
+ "/"
+ "db"
+ "?"
+ "noDatetimeStringSync=true&useUnicode=yes&characterEncoding=UTF-8&unique_checks=0";
that's the limitation, sorry for not pointing that out earlier.
According to mysql docs, there is no possibility to set the unique_checks setting, i guess i need to look for other solution than URL parameters (Joachim, thanks for reminding me that these things are called "URL parameters" - help a lot while googling :)

I want spring to search an image under path: /upload-dir/ID.jpg
ID is a variable that depends on the object's id.
Ive made something like this:
th:src="|#{/upload-dir/} ${dog.id} .jpg|"
but this is not working at all. I beg for any advice how to make it work :)
You can use the following structure to do so.
th:src="#{'/upload-dir/' + ${dog.id} + '.jpg'}"
I ran appScan on my application. I can see most of the Validation.Required issues for String objects. But, not sure what validation the appscan is expecting here. we have tried with null and empty check still there is no use. Please any one let me know what validation appscan expects on a string object.
String tableName = this.request.getParameter(TABLE_NAME);
session.setAttribute(tableName + "_" + parentTableName + "_editColumnMap", editableColumnsMap);
Please let me know if you need any more information
The major goal of mitigating Validatoin.required finding is to validate against malicious input. Check in your code if any variable can be set to a value that can be controlled by a malicious user. Any input taking from outside of your system should be validated or sanitized using white-listing: https://www.owasp.org/index.php/Input_Validation_Cheat_Sheet#White_List_Input_Validation
This is probably a pretty simple issue but since I'm working with 1.3 IDE I can't use the most common method to do this.
String at_cmd_response = atc.send("AT+CMGS=\"+35111111111\"\r");
I need to introduce a string called number which holds a number like "35191xxxxxxx" in at_cmd_response. To do so, I've seen the String.format method but I can't use it due to my IDE.
Is there another way to do this?
Thanks
Simple String concatenation (+) will work:
String at_cmd_response = atc.send("AT+CMGS=\""+number+"\"\r");
Its looks like you have a modem and want to send some commands... like send a SMS or make a phonecall or similar :-) ...
now to the question:
you need to concatenate the modem command with the parameter
in java those are strings and can be concatenated using the unary operator +
like:
"AT+CMGS=\"+yourPhoneNumber+"\"\r"
example:
String yourPhoneNumber = "+35111111111";
and now call the method
atc.send("AT+CMGS=\" + yourPhoneNumber + \"\r");
I use below code snippets for web element locators in Selenium.

Also for rest assured,
If I want to parameterize 3f1dd0320a0a0b99000a53f7604a2ef9 value of below URL.
https://pineapples.com/api/sn_sc/v1/fruit/items/3f1dd0320a0a0b99000a53f7604a2ef9/submit_producer
So I declared it in to a variable and using “+sys_ID+” I pass it.
String sys_ID = "3f1dd0320a0a0b99000a53f7604a2ef9";
RestAssured.baseURI = "https://pineapples.com";
RestAssured.basePath = "api/sn_sc/v1/fruits/items/"+sys_ID+"/submit_producer";
I set textures in each individual file, this is the non efficient way to set it
this.setUnlocalizedName("ItemName");
this.setTextureName("MyModName:ItemName");
This way made sense to me, but didn't work:
this.setUnlocalizedName("ItemName");
this.setTextureName(OtherClassName.MODID + ":" + this.getUnlocalizedName());
the 'OtherClassName.MODID' is referring to a variable in another class that contains 'MyModName'
The this.getUnlocalizedName() gets the UnlocalizedName that has been declared, 'ItemName'
Any help? I am not sure why it doesn't work.
getUnlocalizedName is slightly weird - it returns the string you passed into setUnlocalizedName, but with "item." at the start. The joys of working with deobfuscated code...
This would work:
String name = "ItemName";
this.setUnlocalizedName(name);
this.setTextureName(OtherClassName.MODID + ":" + name);
Note that it's not more efficient as in faster to run, but it might be faster to write if you change the item name a lot.
I established connection to a SAP Server and I would like to print a list of BAPIs in my Java program. I am using sapjco3.jar.
Is there any way to do it?
You can also use the function module SWO_QUERY_API_METHODS. The following code snippet works with JCo 2:
IFunctionTemplate functionTemplate = Repository.getFunctionTemplate("SWO_QUERY_API_METHODS");
JCO.Function function = functionTemplate.getFunction();
mConnection.execute(function);
ParameterList exportParameter = function.getExportParameterList();
System.out.println("exportParameter: " + exportParameter);
ParameterList importParameter = function.getImportParameterList();
System.out.println("importParameter: " + importParameter);
ParameterList tableParameter = function.getTableParameterList();
System.out.println("tableParameter: " + tableParameter);
As far as I know, there is no "BAPI to get a list of BAPIs", so this would be a non-trivial task. You could try to use RFC_FUNCTION_SEARCH to search for function modules named BAPI*, but that's not guaranteed to give you a) only official BAPIs and b) all of the official BAPIs...
You can use the BAPI_MONITOR_GETLIST to get a list of all BAPIs in your system together with meta data.
You could make an ABAP function searching for all RFC functions in table TFDIR, with FMODE ='R' (remote). However, This will give you all remote-callable function, not only BAPIs.
