Description. Howard Schreiers book explains and illustrates the use of PROC SQL in the context of the SAS DATA step and other SAS procedures such as SORT, FREQ, MEANSSUMMARY, APPEND, DATASETS, and TRANSPOSE whose functionality overlaps and complements that of SQL. I have a stored procedure that returns 80 columns, and 300 rows. I want to write a select that gets 2 of those columns. Something like SELECT col1, col2 FROM EXEC. Page Nos. Severity Description 33 The CREATE TABLE statement should be preceded by a PROC SQL statement and followed by a QUIT statement. A consistent code style guide for SQL to ensure legible and maintainable projects. Using a side by side approach, this concise reference guide includes many extensively explained examples showing equivalent DATA step and SQL code. It enables SAS users to take advantage of existing SAS skills and knowledge while learning about SQL. Discussions cover the differences between SQL and the DATA step as well as situations where SQL and the DATA step are used together to benefit from the strengths of each. Reviews. Read the first set of reviews about this book. Errata Page Nos. The CREATE TABLE statement should be preceded by a PROC SQL statement and followed by a QUIT statement. The RUN statement which appears in lower case should be in upper case. The first SELECT statement should be preceded by a PROC SQL statement and followed by a QUIT statement. The hypothetical CREATE TABLE statement should be preceded by a PROC SQL statement and followed by a QUIT statement. There are obviously three statements in the code. The first sentence of the paragraph which follows should read Before we look at the effect of this step which comprises, apart from the PROC and QUIT statements, a single statement terminated by a single semicolon, lets look at the syntax and compare it to that of the join. The running head chapter indicator preceding the page number is incorrect. In each of the two SELECT statements, whitespace is needed between the FROM and GROUP BY clauses.

There should be a blank TITLE statement TITLE after the last SELECT statement. Without it, the last declared title will persist. There should be blank TITLE and FOOTNOTE statements TITLE FOOTNOTE after the SELECT statement. Without them, the last declared title and footnote will persist. The next to last PUT statement is superfluous. Update Multiple Columns Proc Sql Syntax' title='Update Multiple Columns Proc Sql Syntax' />The RUN statements in the PROC DATASETS steps should be indented. In the DATA step, several tokens should be in upper case, as in. DO Measure 1 TO 3 OUTPUT END. The PROC DATASETS steps should be terminated with QUIT statements. Each of the two INSERT statements should be preceded by a PROC SQL statement and followed by a QUIT statement. The RUN statement which appears in lower case should be in upper case. The SQL code should be preceded by a PROC SQL statement and followed by a QUIT statement. To align tokens in the code, one space should be removed before the slash in the BREAK statement. The CREATE TABLE statement must be followed by a QUIT statement. The statements must be submitted together in order to get accurate timings. Severity is reflected in the number of asterisks. One asterisk indicates a minor issue such as a spelling or grammar mistake, or a deviation from style. Two asterisks indicate ambiguity or other source of possible confusion. Three asterisks indicate an incorrect statement or code which produces incorrect results where the mistake is fairly obvious. Four asterisks indicate a subtle mistake. Readers Questions and Comments. Just edit this page or use the discussion tab. Q Some of the examples deliberately trigger ERROR conditions. How does one prevent those from snowballing and interfering with subsequent examples. A Within a PROC SQL session, run. At the global level, run. OPTIONS NOSYNTAXCHECK OBSMAX. Q Is there a second form of CASE, parallel to SELECT expression etc. A Yes. To illustrate, suppose that the destinations for the field trips depended only on age, with all 1. Adjusting the CASE structure in the book to these rules would result in. CASE WHEN age1. 1 THEN Zoo. WHEN age1. 2 THEN Museum. ELSE None. This can also be expressed more compactly as. CASE age WHEN 1. 1 THEN Zoo. WHEN 1. 2 THEN Museum. ELSE None. Q What happens when PROC PRINT or a DATA step is fed zero observationsA In both situations the behavior is like that of PROC SQL. If you run. PROC PRINT DATApreteen. NOTE No observations were selected from data set WORK. PRETEEN. an empty zero observation data set is created. Q Is this usage of DISTINCT within a function call allowed in clauses other than SELECTA Why not Heres an example. SELECT sex. FROM sashelp. GROUP BY sex. HAVING MEANDISTINCT age GT 1. Names less cryptic than u. The mnemonic intent not explained in the book is U for unique that is, keys which do not repeat and M for multiple keys which do repeat. Q The documentation says that NOT can be coded directly before EXISTS or IN to negate the result of the comparison. Are there similar constructs for the other subquery contexts ANY, ALLA. ANY and ALL themselves cannot be negated, but the comparison operators to which they bind can be negated, or the overall evaluations can be negated. For example. SELECT name. Apeiron Game For Pc here. FROM sashelp. WHERE SUBSTRname,1,1 EQ ANY SELECT sex FROM sashelp. This returns only the name Mary, the only name in the table beginning with F or M. Now replace EQ with NE. SELECT name. FROM sashelp. WHERE SUBSTRname,1,1 NE ANY SELECT sex FROM sashelp. As long as the subquery returns at least two distinct values for SEX, the condition will always be true since any initial will be not equal to one or the other or both. Thats the case here, so the result set contains all of the names found in the source table. Finally, use EQ but prefix the whole expression with NOT. SELECT name. FROM sashelp. WHERE NOT SUBSTRname,1,1 EQ ANY SELECT sex FROM sashelp. This returns all names except Mary in other words, the complement of the first result. Q Where are ANY and ALL documented They dont appear in the SQL Procedure Component Dictionary. A ANY and ALL are documented only by example, as part of the explanation of subqueries. See the section Query Expressions Subqueries in the sql expression page, which does appear in the SQL Procedure Component Dictionary. Q Exactly how can the missing values be replaced with zeroesA Use the COALESCE function, with the subquery as the first argument and zero as the second. SELECT fname. age. COALESCESELECT COUNT. FROM classgirls. WHERE moregirls. AND moregirls. fname classgirls. GROUP BY classgirls. AS Same. Age. FROM moregirls. QUIT p. 1. 19 The same table name UNIONALL was used in an earlier example. Elsewhere, SQL and DATA step examples use the same names for their output. It would be better to have distinct names for all these tables. Q The cited section on Concepts appears to be nonexistent. Where is the content A The author would appreciate any information about that. The section did appear in earlier editions of the Procedures Guide, such as 9. Q How can PROC SQL drop the table when PROC DATASETS has just done exactly that A The two steps are eitheror alternatives. So to see both in action, the target table has to be re created. Here is a briefer example. DROP TABLE demo. pp.
