Equals(=) vs. LIKE <p>When using SQL, are there any benefits of using <code>=</code> in a <code>WHERE</code> clause instead of <code>LIKE</code>?</p>
<p>Without any special operators, <code>LIKE</code> and <code>=</code> are the same, right?</p>
| <p>The equals (=) operator is a "comparison operator compares two values for equality." In other words, in an SQL statement, it won't return true unless both sides of the equation are equal. For example:</p>

How to map 2+ entities to same table in .NET Entity Framework? <p>I'm trying to create 2 entities that operate as different views on the same underlying db table.

When to upgrade libraries <p>I work with a lot of open source libraries in my daily tasks (java FYI). By the time a project comes close to maturing, many of the libraries have released newer versions. Do people generally upgrade just to upgrade, or wait until you see a specific bug? Often the release notes say things l... | <p>The rule for us is to stay up to date before integration testing but to permit no changes to any library once we're past this point. Of course, if integration testing reveals flaws that are due to an issue with a library that has been fixed, then we'd go back and update. Fortunately, I cannot remember a situation ... |
How to display 1 instead of 01 in ToString(); <p>I am using the format ToString("0,0") to display a number like <pre>5000 as 5,000</pre> but if the number is 0 - 9, it displays 01, 02, 03, etc. Does anyone know the correct syntax so it does not display the leading 0?</p>
<p>Thanks,
