By Melanie Caffrey Part 3 in a series on the basics of the relational database and SQL Part 2 in this series, Modeling and Accessing Relational Data Oracle Magazine, NovemberDecember 2. When your logical models and physical implementations use meaningful entities and well chosen datatypes, you have multiple options for accessing the data. This article focuses on the purpose and anatomy of the SQL SELECT statementalso called a queryand explains how to use Oracle SQL Developer and Oracle Application Express to construct queries and view their results. Although Ill briefly review the concepts covered in Part 2, I encourage you to read that installment before starting this one. Destination Treasure Island Crack Game more. It All Begins with a Query. The goal of writing a SQL query is usually to get the answer from the database to a question or questions. For example, you might want to ask How many employees work in the accounting department Of those employees, which ones are currently working on multiple projects Which employees working on multiple projects in the accounting department have received a salary increase between their date of hire and today, and which employees haventYou obtain the answers to these questions by using a SQL SELECT statement. A SELECT statement has at least two parts the SELECT list and the FROM clause. The SELECT list specifies one or more columns or expressions, to be explained in subsequent installments of this seriesselected from one or more tablesthat you want to display. The FROM clause lists the tables from which your desired column data should be obtained. Know Your Data. Before you write a SELECT statement, you must determine which table or tables contain the information of interest. For example, if you want to know all employees hire dates, you must first determine which table contains employee information. Perusal of your schema diagram reveals that employee data is in a table called EMPLOYEE. You can then use the following SELECT statement. SELECT firstname, lastname, hiredate. FROM employee. The SELECT list in the above statement specifies three columnslisting the first name, last name, and date of hire for every employee contained in the EMPLOYEE table, which is specified in the FROM clause. To specify multiple columns in a SELECT list, you separate the column names with commas a good practice is to insert a space after each comma for readability. When the above statement is executed, the result set is a list of all the values found in the firstname, lastname, and hiredate columns of the EMPLOYEE table, as shown in Listing 1. Code Listing 1 Code Listing 1 SELECT statement result for three columns. SELECT firstname, lastname, hiredate. FROM employee. FIRSTNAME LASTNAME HIREDATE. Frances Newton 1. SEP 0. 5. Emily Eckhardt 0. JUL 0. 4. Donald Newton 2. SEP 0. 6. Matthew Michaels 1. MAY 0. 7. Everything with a Mere If you want to display all the columns for a particular table, you can use the asterisk wildcard character as the SELECT list instead of typing the name of every column. For example. FROM employee. When this statement executes, the result set displays the columns in the order in which they are defined in the table, as shown in Listing 2. Code Listing 2 SELECT statement result for all columns. Torrent 90. FROM employee. EMPLOYEEID FIRSTNAME LASTNAME HIREDATE SALARY MANAGER DEPARTMENTID. Frances Newton 2. Emily Eckhardt 2. Donald Newton 2. Matthew Michaels 2. This is the same column order you see when you issue the DESCRIBE command or when you click the Columns tab in Oracle SQL Developer, as shown in Listing 3. Code Listing 3 DESCRIBE result for the EMPLOYEE table describe employee. Name Null Type. EMPLOYEEID NUMBER. FIRSTNAME VARCHAR23. LASTNAME VARCHAR23. HIREDATE DATE. SALARY NUMBER9,2. MANAGER NUMBER. DEPARTMENTID NUMBER. You should use the asterisk wildcard character primarily for ad hoc queryingwhen you want an answer from the database that you have not already asked for via programmatic code. When you include SELECT statements in programmatic blocks of code which youll learn about in subsequent articles in this series, it is a good practice to list your columns of interest by name in your SELECT lists. SELECT with Oracle SQL Developer. In Oracle SQL Developer, an easy way to construct a SELECT statement is to drag and drop a table name from the TABLES node in the Connections Navigator into the SQL Worksheet. This action automatically creates an editable SELECT statement in the SQL Worksheet whose select list includes all the columns in the table. Figure 1 shows the result of dragging and dropping the EMPLOYEE table into the Oracle SQL Developer SQL Worksheet. Figure 1 Result of dragging and dropping the EMPLOYEE table into the SQL Worksheet. Figure 2 shows the SQL Worksheet icons. Figure 2 The SQL Worksheet icon tool bar. The leftmost green arrow in Figure 2 is the Execute Statement icon. When you want to obtain the results for a single statement, place your cursor anywhere on the statement line and click the Execute Statement icon. The results appear on the Results tab, as shown in Figure 3. Figure 3 The Results tab in the SQL Worksheet. In the tool bar, the small green arrow superimposed on the image of a piece of paper is the Run Script icon. By clicking it, you execute a SQLlus like script consisting of multiple statements as Ill illustrate in the next article in this series. The results are displayed on the Script Output tab, as shown in Figure 4. Figure 4 The Script Output tab in the SQL Worksheet. Build and Run a SELECT Statement with Oracle Application Express. Descargar Libro Pdf Halo there. You can also construct a SELECT statement in the SQL Commands window of Oracle Application Express SQL Workshop, a Web based interface to the database. The SQL Workshop SQL Commands window has no drag and drop facility, so you must type your statement explicitly. Next, click Run to see your result set in the Results section of SQL Workshop, as shown in Figure 5. The results format is similar to that used on the Results tab of the SQL Worksheet, as you can see by comparing Figure 5 with Figure 3. Figure 5 The Results section in SQL Workshop. Constructing a SELECT statement in the SQL Commands window of the SQL Workshop in Oracle Application Express is similar to constructing a SELECT statement in SQLlus as I will illustrate in the next article in this series. Eliminate Redundancy with Distinction. As you know from previous installments in this series, one of your database design goals should be to eliminate redundancy. Sometimes, however, the way you select data might cause the results to include duplicate values. Use of the DISTINCT or UNIQUE keyword in your SELECT list, however, helps you eliminate duplicate data in your result sets. In the example in Figure 6, four rows are returned yet only two employees are assigned to departments. Frances Newton and Emily Eckhardt have NULL values for DEPARTMENTID. Figure 6 Employee first and last name data with corresponding departments. If you want to display only the distinct or unique DEPARTMENTID values in the EMPLOYEE table, you can construct a SELECT statement like the one in Figure 7. Figure 7 A DISTINCT list of the DEPARTMENTID values in the EMPLOYEE table.
