The scale has a range from 0 to p (precision). The scale can be specified only if the precision is specified. By default, the scale is zero.<\/li><\/ul>\n\n\n\n<p>The maximum storage sizes vary, depending on the precision as illustrated in the following table:<\/p>\n\n\n\n<figure

take an example of using the <code>DECIMAL<\/code> and <code>NUMERIC<\/code> data types.<\/p>\n\n\n\n<p>First, create a new table that consists of two columns: one decimal and one numeric:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-4\" data-shcb-language-name=\"SQL (Structured Query Language)\" data-shcb-language-slug=\"sql\"><span><code class=\"hljs language-sql\"><span class=\"hljs-keyword\">CREATE<\/span> <span class=\"hljs-keyword\">TABLE<\/span> test.sql_server_decimal (\n    dec_col <span class=\"hljs-built_in\">DECIMAL<\/span>

class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>Second, insert a new row into the <code>test.sql_server_decimal<\/code> table:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-5\" data-shcb-language-name=\"SQL (Structured Query Language)\" data-shcb-language-slug=\"sql\"><span><code class=\"hljs language-sql\"><span class=\"hljs-keyword\">INSERT<\/span> <span class=\"hljs-keyword\">INTO<\/span> test.sql_server_decimal (dec_col, num_col)\n<span class=\"hljs-keyword\">VALUES<\/span>\n    (<span

class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>Fourth, the following example attempts to insert a new row into the table with values that exceed the precision and scale specified in the column definition:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-7\" data-shcb-language-name=\"SQL (Structured Query Language)\" data-shcb-language-slug=\"sql\"><span><code class=\"hljs language-sql\"><span class=\"hljs-keyword\">INSERT<\/span> <span class=\"hljs-keyword\">INTO<\/span> test.sql_server_decimal (dec_col,

class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">sql<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>SQL Server issued an error and terminated the statement:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-8\" data-shcb-language-name=\"SQL (Structured Query Language)\" data-shcb-language-slug=\"sql\"><span><code class=\"hljs language-sql\">Arithmetic overflow error converting numeric to data type numeric.\nThe statement has been terminated\n<\/code><\/span><small class=\"shcb-language\"

class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">sql<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>In this tutorial, you have learned how to
