Check Sql Server database is Case Sensitive or Insensitive (Collation)

November 21st, 2008 admin

If the collation property of a data base is

1.Latin1_General_BIN its case-sensitive
2.SQL_Latin1_General_CP1_CI_AS or Latin1_General_CI_AI its case-insensitive

There are two ways to find out the SQL Server Database Collation

1. Using DATABASEPROPERTYEX

DATABASEPROPERTYEX gets the current setting of the specified database option or property for the specified database.

Syntax :-
DATABASEPROPERTYEX ( database , property )

SELECT DATABASEPROPERTYEX(‘testdb’, ‘Collation’)

This returns the testdb Database Collation property value say if this testdb is a case-sensitive database then it returns

Latin1_General_BIN

2.Using Sql Server Management Studio

Step 1 : Open Sql Server Management Studio.

Step 2 : Right Click on database and click its properties


After clicking the properties you get a database properties modal box such as

The red box shows the collation property value of that database.

Conditional Tags in JSP

November 14th, 2008 admin

The if tag allows the conditional execution of its body according to the value of the test attribute

<c:if test=”${not empty details.add}”>
It is Not a Empty ArrayList
</c:if>

<c:if test=”${empty details.add}”>
It is a Empty ArrayList
</c:if>

The choose tag performs conditional block execution by the embedded when subtags. It renders the body of the first when tag whose test condition evaluates to true. If none of the test conditions of nested when tags evaluates to true, then the body of an otherwise tag is evaluated, if present.

<c:choose>
<c:when test=”${bank.account== ‘saving’}”>
Saving Account
</c:when>
<c:when test=”${bank.account == ‘RD’}”>
RD Account
</c:when>
<c:when test=”${bank.account == ‘salary’}”>
Salary Account
</c:when>
<c:otherwise>
…
</c:otherwise>
</c:choose>

Login failed for user ‘(null)’. Reason: Not associated with a trusted SQL Server connection.
