If you do not have the icon located on your desktop, perform the following steps. If you installed the SQL Developer icon on your desktop, click the icon to start your SQL Developer and move to Step 4. But login.sql is still used as in sqlplus, so we can put all ALTER SESSION SET NLS_… in it. The first step to managing database objects using Oracle SQL Developer 3.0 is to create a database connection. Currently I don’t think we can set the territory from the command line environment. data two environment variables should be set: export TMPPROJECT/HOME/tmp. NLS_LANG sets characterse, language and territory. How To Migrate Non-Oracle Databases For Which a SQLDeveloper or Migration. So, when you will port your sqlplus scripts to the new SQL Developer command line, don’t forget to check the NLS_LANG you were using and set the right Java environement. The TYPE attribute lets you declare a constant, variable, field, or parameter to be of the same data. Here is how to set the characterset in Java: My DOS window is in PC850 characterset (I’ve blogged about that recently). What if I want to keep my local and display the special characters correctly? When you have a non-english locale and want to have SQL Developer in inglish, you just run: sqldeveloper.exe -Duser.language=en -Dfile.encoding I had the date in French and because it’s unicode it displays bad characters on my DOS window. The query does not need a TODATE for variable x since I have already declared it as type DATE in the stored procedure and populated it with a date. For SQL Developer you put it on the command line as ‘-Duser.language=en’ and for the command line you can set it in the DEBUG environment variable (this is for the alpha version – may change in the future). VARIABLE string VARCHAR2 (10) VARIABLE dt DATE VARIABLE year NUMBER BEGIN :string : Hello :dt : DATE :year : EXTRACT ( YEAR FROM :dt ) END / SELECT FROM tablename WHERE cola :string AND colb :year However, here you arent using PL/SQL except for the middle BEGIN. If I use the variable to generate explain plan, will it have an impact on the plan For example my original query is: select c1 from t1 where c1 :x c1 is type DATE. You can change it with the user.language option. Duser.languageīy default java uses the language that is set by your operating system locale. So here is how to set the language and characterset with the java options. That version comes with a command line (in beta) which goal is to be fully compatible with sqlplus but running in java, and having a lot more features.īecuse it’s connecting with thin java driver by default, it doesn’t use NLS_LANG. If the value of a defined variable extends over multiple lines (using the SQLPlus command continuation character), SQLPlus replaces each continuation character and carriage return with a space. I’m using Oracle SQL Developer 4.1 Early Adopter for a while and I like it. SQLPlus will not prompt you for the value of variable in this session until you UNDEFINE variable.
